An ADCO cover is another option, but we plan to camp locally on a frequent basis. We have a wonderful state park only 20 minutes from home. I don't want the hassle of installing/removing that huge thing that often. The previous owner gave us his cover, but it doesn't have an opening for the entry door. That's another pain when wanting to access the trailer while at home.
Strongly disagree about the cover being a hassle to put on/take off. Takes me all of 20 - 30 minutes. The teqnique is to have a large rubbermaid garbage can. When the cover is on, you simply unhook all the straps that hold it at the botom, then get on top ot the TT and pull it up on the sides, folding it to the center. You then get down and pull the cover into the (clean) trash can folding it accordion style. Put the lid on and your done. Putting it on you follow the same steps in reverse form the rear of the TT since the front of the cover is on top. You get some pool noodles to cover sharp edges such as gutter extensions and door stops. When the cover is on, you store the trash can inside the TT's door. The new ADCO covers have zippered sections so entry while covered is easy. The other benefit is you wont have all the debris from those trees staining it - and boy will it be stained. Then the hassle will be forever cleaning black streaks and tree stains. Good luck in whatever you decide.
