I'm in NH, and I quit covering the trailer after only one season. Here I was with my shiny new TT, so I figured I would cover it to keep it perfect.
I hated putting it on. I hated taking it off. I had no where to store the gigantic bundle of fabric, and worst yet: with it covered I couldn't run out the slides for a super bowl party.
I craigslisted my ACCO cover the next spring.
