I am in the process of converting an old boat trailer into a cargo trailer to haul our camping gear. I have a section about 64"x96" for the camping gear. The front section which is a triangle I thought about enclosing this area for the coolers and other food storage, with the idea that it would have doors to close to keep the bears and other critters out. I also thought about insulating it to help conserve ice will camping. Anybody do something like this?
