Someone i know asked me about this, He had a nice TT. He asked me what i did for storage and i told him "in doors" and gave him the the phone number to call.. He said it was cheaper to buy a cover for winters. Last fall he bought a cover and over the windy winter the cover shredded and tore up the corners of the roof and pulverized the decals. Now i see a brand new camper in the driveway, Not sure why insurance didn't cover it or why he ended up with a new tt..
Do a hard cover, Stay away from toss over covers.. Mine camper goes indoors up at the local RV dealer. Some day i want to build a pole roof,(not sure what to call it). like the guy up the street. His doubles as a picnic area in the summers and camper storage in the winters. It is a nice setup. Pretty similar to this. http://rvtravel.com/blog/rvnow/2007/...ires-some.html
