I've been thinking about upgrading to an enclosed trailer. I like that things will be reasonably secure from theft and protected from the weather. I'm thinking of going with one that has a side door, and maybe tandem axles. I'd eventually like to fit a ZTR/Stander and a 48" WB with some room left over for tools and trimmers (room to walk around I guess). It would also be a nice "canvas" for advertising. Other than price, smell and heat... what are some drawbacks of using an enclosed? I'm also looking for recommendations (brands).
