Good thread... I have to re-deck my trailer at some point. The wood is cupping and splitting as it is always sitting over a grass/moisture area. I should really find an area and take the grass/top soil off, lay plastic and a layer of gravel to prevent this from happening again.

Even better to keep em' indoors in an outbuilding if available. My old hanger building is good for that but most people probably don't have a place to store a trailer, especially a larger one.

Dryer climate verses wet climate is not as hard on a trailer being kept outside but eventually the elements anywhere will do some damage even if stored inside a building, no way around that.
Extreme cold and heat cannot be stopped even by a building unless it's maybe controlled thermostatically.
