I have stayed in trailers, motor homes, campers, they okay until everyone comes in with wet clothing and attempts to dry it. There also little room to move so you better like each and the smell a whole lot. Other than a 24' x 42' x 2 story hunt camp with full services of electrical and plumbing, the next best set up I owned was a 14' x16' canvas prospectors tent, wood stove for heat, propane lights, and a separate cooking section to control humidity, with "two" tarps over the whole thing. Handles 4 men plus gear very well. And you can get your stuff dry when your cold and wet, and that little factor is real important. Moose hunted from one of these set ups for 15 yrs in all sorts of nasty weather without issue, very comfy.
I have seen several well thought out and home made trailer setups that worked for the makers and users it appeared very well. But space is tight and everything including the hunters has its place. Boils down I guess to what ever works for you and your buddies. But you will find whatever you stay in being warm and dry tends to take top priority real quick.
Just my two cents from experiences.
