What You Need to Know About De-winterising Your RV


Winters Can Be Hard

De-Winterizing our RV

Well, fellow RV’rs.  I know it’s only January but I’m sure some of you are starting to get cabin fever again and your thoughts are turning towards preparing for the next camping season.

Some of you may have gotten your feet wet last summer with a new RV and you’re wondering what you need to know about de-winterizing your RV.   Your thinking about starting to plan trips with the family,  attending special events or touring some of the places you’ve always wanted to see but you want to make sure that everything is in ship-shape before you hit the road.

Many of you live north of the equator in the cooler climates like the Northern U.S. and Canada.  Pretty much anyone living north of the tropic of cancer, especially near the Canadian border and further north, around the globe, are going to have RVs the have been hibernating over the late Fall and Winter and it’s going to need some TLC before that first trip of the season.

Whether it’s the trip planned for the end of June, Spring break, (North America), or a long weekend in May, no one wants to be surprised by problems that should have been looked after beforehand.

Some of these things can be looked after personally, and other things are best left to someone who knows what they are doing:  the tech at your local RV dealership.

Whatever your situation, here are some things to consider when it comes time to get your RV out of storage mode.

So let’s get down to it, shall we?

Checking the Roof

First,  let’s start with the exterior of your RV with the first place we want to inspect; the ROOF:

  • Some units don’t come with a ladder, (Don’t know why manufacturers do that.  Seems to make more sense to have that included as standard equipment),  so find a folding step ladder that’s safe and the right height.  I would recommend one that is at least 8 feet tall.  The right height is important because you don’t want to struggle and risk falling.  This could ruin a very promising summer.
  • Without actually climbing on the roof make a visual inspection of the roof vents, air conditioning cover, antenna, sewer caps, and skylights if you have them and the overall roof condition.   Pay particular attention for cracks or lifting of the sealants that are around the different items on the roof and along the front, back and both side edges where the roof meets the rest of the trailer.
  • If any of the sealant material needs to be replaced, do so.   Check with your local RV dealership/service center for the proper sealant that should be used.   Also, make sure that you have a couple of pieces of plywood that can be placed on the roof and moved easily for weight distribution and protection.  I recommend that you use at least 1/2″ thick, (3/4″ would be better),  12-15″ wide and about 48″ long.  Two pieces will allow you to move one while standing on the other.  And make sure that the edges are free of chips that stick out, they will easily put a hole in the rubber roof.


NOTEWhen choosing a sealant for the roof of your RV make sure it is the correct one.  There are many different products out there so if you are unsure about which one to use ask your RV dealer.  They will recommend the correct sealant.

Dicor 501LSW-1 Self-Leveling Lap Sealant is one I would recommend.  It’s not that expensive, is self-levelling and is one of the top-selling roof sealants on the market.

One other thing to consider when re-doing the roof sealant is DON’T skimp on the amount you put down.  Look at what is already there and use this as an example.

The Rest of the Exterior

After we are done with the roof we want to inspect the rest of the exterior which includes:
  • the mouldings and sealant around the side panels,  the caulking around the windows, the storageexterior windows door trim, the water connections, entrance doors, outdoor access panel to the water heater and outdoor shower, range hood vent etc.  This is something you might want to do a few times throughout the season just to make sure that everything is tight and there are no gaps or cracks where sidewalls and mouldings come together that could let in water.


NOTETo avoid getting sealant on the window trim, exterior panels, and other areas where there is a moulding, mask off the area in question.  When you remove the tape the mess goes with it and you have a nice clean line.  You can also smooth it out with a wet finger and lightly pass over the area where you have replaced the sealant.


  • Lubricate the hinges on the storage and entrance doors and locks and make sure to put some on the slide-out/fold-down steps as well.  A little silicone spray, or “3 in 1” will do the trick here.  And a little in the locks of all the compartments and the entrance doors are also a good idea.
  • Make sure you check all the running lights and replace any that are not working.   You don’t want to get rear-ended by someone because your brake lights weren’t working.  Not only would you be mostly, or totally responsible for your own damage but you would also be responsible for any repairs to the other vehicle and no one wants that when they’re on a vacation.
  • Most RV tires have a life span of 3-5 years depending on use so check your tire pressures to make sure they are all pressurized properly.  Also, check for wear and tear like cracks in the sidewalls and thickness of the tread.  The last thing we want to end up with is a flat tire but if it happens and you have duel axels on your RV/trailer then one of these will make the job easier.


NOTE:  Here is a picture of what your tires should and shouldn’t look like when they are inflated.



  • Check the wheel bearings and the bushings on the suspension.  Some bushings are just plastic and wear out quickly.  This can happen in only a few thousand miles and can be upgraded using a Heavy Duty Suspension replacement kit, (I’ll be writing about this in a future blog), which has brass bushings, heavy-duty plates and zerk fittings for easy lubrication.  Unless you are good at this sort of thing and have the right equipment, this should be done by a professional.   If you have had your trailer/RV for a while this may be a good time to have this work done.
  • Check your battery fluid levels, the charge, and voltage level before you hook it up. It is recommended that you do a load check as well.  It is also recommended that you wear eye protection and proper clothing.   However, if you don’t feel safe doing this yourself,  have your dealership/service dept. take care of this.   It’s better to be safe and spend a few dollars rather than risk injury.   When you connect the battery use a little dielectric grease or something recommended by your dealer.   This will help prevent corrosion.   Hook up the wires properly, doing the ground wire connection last.
  • Make sure you check all the equipment used to connect the trailer/fifth wheel, to the tow vehicle for wear and tear and replace it if necessary.  If you’re not sure of what to look for, have your service technician do a check.


Checking Out the Interior

With the outside checks done it’s time to check out the interior.   Don’t just have a look around and presume everything looks alright.  Things can change during the time spent in storage.  As an example, I had to replace a full set of upper cabinet doors and three others, as well as re-do all the mouldings around the interior countertops.  This was due to high humidity inside the trailer and cost me about $1300 to fix.  So,
  • Check the cupboard doors and drawers, open them,  check inside with a flashlight to see if there is anything in there that shouldn’t be,  like mice or their droppings or, worse yet, water damage.  If you have no way to hook your trailer up to power,  buy two or three dehumidifiers for your unit.  The cost is minimal and will save you unneeded repairs in the future.  I have four in my 25 ft. trailer and they are working well.
  • Check the ceiling and wall panels for any moisture damage as well.  Look for brown discoloration or bubbling/swelling on the surface.
  • If you are able to plug into city power, check your appliances, wall plugs, GFI plugs, monitor panel and interior lights.  Check the bathroom fan.
  • If you have room, or when you do, pop the slider'(s) and the awning out and in to make sure they are working properly, lubricate moving parts and check the seals around the sliders, (a silicone lubricant will help protect the seals from cracking and also from the sun’s UV rays.
  • Test and make sure your smoke and carbon monoxide detectors are working.  Make sure the fire extinguisher is fully charged as well.  Replace any batteries or components that don’t work and if you don’t have any of these items purchase them right away and install them.  They will save your lives.
  • Don’t forget to check the PROPANE system.  Check all connections on the tanks, (are the date stamps within the current ten year period?  I’ve been stung a couple of times when I thought everything was good to go.), and you may want toRV propane tanks have a pressure test done for your own safety.  When this is done, open the valves on the tanks and turn on the stove to make sure it is working properly.
  • If, or when, you have a water source available, flush water through your plumbing system, opening up the cold water taps and then the hot water taps and the shower taps and flush thoroughly. do this for the outdoor shower as well.   If there is an odour of foul taste when running the water there are products available to clean and deodorize the system.   These are available at your local dealer.
  • And finally, one last thing.  Check all the drains and make sure the GREY and BLACK WATER tank valves are working smoothly and don’t leak when you close them up.


Final Remarks

If this seems like a lot, or you don’t have the time, this can all be done at your local service center. They will, of course, charge you for this service but, they will do a good job and perhaps catch a thing or two you/I may have missed.   Take this list with you and, hey, if I missed something, by all means, LET ME KNOW.   I’ll be happy to update my blog.

If you own a Motor Home make sure you check all the motor fluid levels:  engine oil, brake fluid, power steering, transmission fluid level, windshield wiper fluid and yes, even the battery fluid levels. Check all your exhaust pipes as well and your portable generator if you have one.

As always, if you have a question or comment, tip or trick I would be happy to receive them.  I will answer all the questions and comments ASAP usually in a day or two.

Until then I wish you Happy Camping and Stay Safe,

  1. If you own an RV, you want it to last. Take great care of your RV and it can last a lifetime! One of the best and simplest ways to take great care of your RV is to use of Liquid Roof sealer. This sealer can provide you with the protection your RV roof needs.

    1. Couldn’t agree with you more, Elizabeth but I wonder, is it necessary to do that right after you purchase a new RV or could it wait a few years?

      I wouldn’t think it would be necessary for a new RV but I would consider it after three or four years. Interested to hear your thoughts.


  2. Without actually climbing on the roof make a visual inspection of the roof vents, air conditioning cover, antenna, Sewer caps, and Skylights if you have them and the overall roof condition. Pay particular attention for cracks or lifting of the sealants and use Liquid Rubber to get rid of leakage.

    1. Thank you for your comment, Emma and you’re absolutely right. An inspection can be done from a ladder which will also reduce the chance of damaging the roof by stepping on it. Always check your owners manual for specific directions and maintenance routine. It wouldn’t be there if it wasn’t important.
      It is also a good idea to check all sealants around the windows and doors at least every 3 months just to make sure that everything is still sealed and redo where necessary as it is important to keep water out of the RV because Rot can happen very easily and quickly.

      It’s a privilege to have a business like you leave a comment. Again I thank you and all the best.

  3. Hi Wayne.
    I am impressed to say the least. I have not yet bought an RV but it is a desire of mine. I had no idea there would be this much to check. I am glad you have provided all of these tips. Now I know once I do buy one I need to make sure and check the outside roof all the way to flushing out the water pipes if I find one with water equipped. Thank you so much.

    1. Hi, Melissa and thanks for visiting my website and I apologize for taking so long for replying to your comment. I am also glad you found my post helpful and hope that someday you are able to fulfill your dream of owning an RV.

      I realize that it sounds like there is a lot to do when getting ready for a new camping seasons worth of adventures but, even though it seems a little overwhelming, most of the tasks don’t take very much time. The roof might take 10-15 min and flushing the water lines will only take a few minutes at the most.

      Depending on how often one uses there RV, the only things that need to be checked on a regular basis are the tire pressures and lug nuts and make sure that the roof is clean of debris. I would recommend checking the tires every time you go on a trip and if it’s a long distance to your destination, I would check those pressures and the condition of the tires every time you stop for a washroom visit of a meal.

      One other note. When you purchase an RV, the manufacturer supplies an owners manual that covers pretty much everything you will need to know about the systems in the RV and how to maintain them for a long life. Owner manuals can be downloaded and printed from the manufacturer’s website for free and there is a ton of other helpful information there as well.

      Thanks again for visiting and I wish you many great adventures in the event that you eventually fulfill your dream of owning an RV.


      P.S. If you have any questions or further comments please send them along and I will be happy to respond to them.

  4. Thanks for the tips.

    I do not own an RV but I do know a lot of people who do and they have ran into a couple of these problems. So I will be sure to provide my assistance the next they need it. The knowledge gained is a huge plus.

    1. Hi, Derek and thanks for stopping by my website. And thanks for leaving a comment. Maybe, one day, you will own a trailer or Motor Home and you will be able to use these as well.

      These will be coming in a series of posts over the next few weeks and I will be starting to do some product reviews as well, things like solar panels and satellite TV.

      The more info I can get to people the more they will be able to enjoy their RV experience.

      As always, if you have any questions you know where I am and, by all means, send your friends.

      All the best to you and, again, thanks for stopping by.
