I've seen a number of trailers parked by people's homes that have been tarped year after year. In each case, they wrap the tarp tight to the sides of the TT with that clear plastic stuff that is about a foot wide and is used for wrapping up shipping pallets of boxes. It's available at Home Depot and Lowes on the same shelf where they have moving boxes, package sealing tape, bubble wrap etc. They also place weight on top of the tarp on the roof to keep it from blowing around and rubbing.
I think the idea is that the wrap holds the tarp tight enough to the walls of the TT that it can not rub. Grommet points, etc. would need to be padded or held away from the skin in some way.
If I were to do that with my TT, I think I'd look for something soft like old blankets to completely cover the roof and drape down the sides a foot or tow. Then I'd place the tarp and wrap it. I think having the old blankets or whatever would further decrease the possibility of rubbing and provide a buffer between the tarp and the roof. There is a downside though. If the tarp leaks, even a tiny bit, by the end of the typical upstate New York winter, there'd be a lot of moisture trapped under the tarp.
But I don't tarp. I would love to find indoor or at least sheltered storage around here as the annual snow fall is higher than where we last lived. Unfortunately, Kitty's wonderful steel shelter is not an option.
