Well the first winter of the year is appon us here and i have a storage question.

Does one tarp the roof or leave it bare if storing outside for the snow season?

Coming from the vintage car world there has been pros and con about doing it.....mainly paint and mold damage....what say thee in the world here of
GMC rv's?

If you insist upon tarping, a few things come to mind. One, humidity. Two,
Cold. Three access to the inside of the coach.

I prefer not to tarp it as ive seen to many cars ruined but i see tons of RV's and trailers tarped/covered so i figured id ask the experienced here
for your wisdom being that im new to all things RV.....lol.

I have the same question. Past 2 winters I have not covered it. But my neighbour is giving me some grief over that. I have only 2 options - tarp or
not. Fellow across the road has done a modified tarp - just folded the tarp up to the dimensions of the roof of his trailer and strapped it in place.
Allows for some breathing via the windows I suppose, but keeps the snow and UV off of the roof.

I have heard folks talking about the evils of UV on the paint and the plastics, but I figure since they are exposed during travel (for some of us, not
me unfortunately) for a good 50-100% of the summer months, how much damage can I expect from it during the winter, when the sun is lower and UV index
is so much less. My biggest question would be the effect of the snow & cold directly on the seams and vent & a/c covers. Would I be better to just
cover the a/c shrouds and let the rest go?

I am concerned about condensation & mold/mildew inside being covered with a waterproof, non-breathable sheet of plastic. I am working on trying to
use some collapsible tent poles to create a low dome to elevate the tarp from the roof surface to allow for air movement, but then I have the problem
of wind potentially whipping the thing around, off and down the block!
Just like you, Rich. Looking for advice.

To All:
We bought our first coach in Aug of 1998 and the first winter we covered it
with a 20 X 40 silver tarp. Got some of the very large inflatable donuts
or you can also use a truck inner tube also. Got several to provide an
airspace between the top and the tarp. Brought the sides out at an angle
and staked them to the ground. Still allow me access to the coach.

The following summer I built this RV cover out of (2) 10 X 20 tent
setups. Used the parts to make a 10 X 30 RV cozy to protect it from the
sun and rain. In the winter months I attached side, back and front made
out of the original 20 X 40 tarp. I added length to the legs by using 1
1/4" electrical conduit. Look at the pictures and ask questions if you
need. This lasted from 1999 to 2004 when we move to our present location.
Also had a 30A power plug, sewer dump and water at the coach location.

I am a firm believer on not leaving the coach exposed to the weather both
summer and winter.

That looks very nice! Unfortunately, my little municipality has decided not to allow "portable garage" type structures beyond your front house line.
Since my coach is parked in my front yard, which I had levelled to create a reasonably flat parking area (my driveway is about a 8+ degree slope from
bottom to top end) I can't build anything with legs. I am forced to put something directly on the top. That is why I am looking at those tent poles.


But I like the idea of tubes! Soft and can support a good deal of tension/pressure from tie-downs. Thanks for that! I will look at that. Easier
than the tent pole idea, and will deflate easily for storage. I have a compressor, so can inflate them at will. I can use the tent poles to build a
shelter at the side of the house for the scooters - maybe give my garage back to the car!

Looks are deceiving, the front of the coach is 20' behind the front setback
in that location.

The reason owners of box on a truck SOBs have to tarp them is because they have flat roofs with sharp edges. When the window caulk gives out, the
coach is toast. A GMC roof is one sheet of aluminum with two rounded SMC ends. Have you ever seen water collected on a GMC roof?

You missed one issue:  RACCOONS...

Our 1973, bought new, never had much issue stored outside uncovered for
20 years, other than finally small leaks around back rounded outside
corners - easy to repair once reconditioning began in 2000...

So we were real smart - decided to put on a full motorhome cover to
protect it one year...  Nice cover - but the raccoons liked it even
more.   About a dozen families moved in under that fine cover. Guess the
rear ladder was a piece of cake for them to climb up and down.  Come
spring we had about 5,000# of poop up there!  They tried to eat into the
plastic carrier.  Gave that cover away right quick we did!

Covers are bad enough outdoors with wind abrasion and interior humidity rise to dripping levels during temperature inversions. I bet tarps are worse
as far as abrasion. I would wash coach with a good carwash liquid Mothers California Gold is my preference due to low odor) and truck wash brush on
pole (saves the back), seal leaks, which you need to do anyway, then put a on coat of automotive wax or polish and park it no cover.

I'm with Jonh on this. I do not have inside storage for my coach, so, a good wash and wax in the fall. The only time I covered my coach w as when I
had it stored in a pole barn. Covered it because of all of the birds that flew in and $hit on everything. Since I have stored outside, I don't cover
because wind will flap the cover around and rub on the paint. The other things I do is park it on pieces of 2 X 8 X 18 pieces of lumber to keep it
from sinking into the ground. Also raise the rear as high as it will go to allow good air circulation under the coach. In addition, once a year,
usually in the spring of the year, I put the coach up on ramps. Then spread cardboard strips along the underside of the frame rails. Then using a
squirt can, squirt used ATF on the rear part of the frame around the boggies where the frame is doubled up. Keeps moisture out, and eliminates rusting
of the frame in this vulnerable area. JWID

Sounds like a big job to me - especially w/ a 28’ and then our 26’ to boot. Guess I need to think about it a bit. Maybe a looonng bit!

I've "waxed" a couple of them. Actually buffed out with a Milwaukee angle polisher. First one I used Mcguires cleaner wax. Had enough cut to get
the chalk removed and wax at same time Did not want to do 2 full processes. The roof is hands and knees but you do only one section at a time.
Sides have so much glass that there is less to do than you think. Normally you would have to be very careful not to burn paint with an angle rotary
polisher, but it's tough to hurt Imron. Second one I used modern Zaino All -in-one. Results about same even with heavy oxidation. Going forward I
just use wash and wax and occasionally detail spray. Especially helps on leading surfaces to make bug removal a little easier. The Croftgate Quick n
Slick is my choice as less noxious than any other product I have tried. A lady here is a dealer so I order direct or pickup at the bigger car shows
where she is set up.

Tarpsng or even a custom fit cover is always a big risk. A neighbor about a 1//2mile down the street from me (I am rural) covered his big SOB about 3
winters ago. I stopped by as he was doing it. He was very meticulous in getting everything down tight with bungees and duck tape. A couple of
months later the wind came up caught and that huge cover and is was flapping in the the wind. What a mess. It destroyed the cover and did a lot of
paint damage too. He told me that his comprehensive insurance was going to cover it. I never checked to see if they did.

I like the idea of an awning or roof overhead even if the sides are open rather than a cover. Many fairgrounds allow undercover parking in the winter
because they are not using their buildings for other things. It is something to check out.
