Ramrat I like my trailer, its main purpose is to haul sleds, but I’ve used it for summer and winter camping this past year, and intend to go again this summer. My advice would be to figure out what space you need for the machines you plan to take and then add enough length to store a lot of gear in there too. By the time you put a cabinet/countertop in there, a table to sit around if it’s raining, 2 or 3 cots, some chairs and whatever else you need you’ll end up needing more space than you think. Granted, everything won't be set up when the machines are in there, but the less you have to set up and tear down to put them in there the more enjoyable your trip will be. The other suggestion I would have is if you’re getting an inline, get one 7 ½ feet wide. If you put two cots or fold down beds side by side in a 7’ trailer they are real close to each other and you really can't even walk between them. Do some google searching and you should be able to find a lot of info and ideas.
