Most of these trailers will fit the bill for you and should be in 1/2 ton range (maybe upper range) and definitely in 3/4 ton range. When I came up with the list there were a couple floorplans we are looking at: bunks with a rear dinette or bunks with a rear seating area like a couch. Us parents like to....."kill a few minutes of time at night" every once in a while lol so we wanted a wood door for the master. A surprising amount actually have a real door to the bunkhouse. There's a ton more that have only curtains, but we eliminated them. Crossroads has quite a few bunkhouses that were lightweight with curtains for the master in their Sunset Trail line. Just about all of the trailers below come with an outdoor kitchen. We never looked into the width of bunks since out little ones are quite small, so there might be some singles in there. One thing to point out. The Aspen Trail 3130QBS is now dealer stock only, so they aren't making any new ones.
