Definitely vote for a cover! Mine is just finishing it's 2nd winter season and despite a few tears at the rain spouts and on the roof from the antenna that are easily covered with patches that ADCO will send you for free, it definitely will keep the TT looking new and free from leaks and weathering.. If I get 3-4 years out of it for $250, that is a small price per year for the extra years it will give me on my TT and the fact the decals will not fade and caulk will not dry out. I keep it on from Nov to May and in between my camping trips in the summer. My TT is 30 ft long but I have learned to cover it in less than 45 minutes by myself... without going on the roof! I am certain my TT will last years more because of that small investment! Why be lazy when you spend so much for a TT?.. I want it to last a long time!
