Only because I'm partial to Dutchmen and Keystone brands, here's a couple floor plans from the Keystone Outback trailers. One is a 5er the other is a TT. Notice the floor plans are very similar. The advantage of the 5er is the extra storage in basement area. The advantage of the TT is, it's a lighter unit.
You said noting about kids, so I'm assuming it's just you and your spouse. If that's the case, you don't need bunks and all that. The two models below are similar, although the bed is in the front and the closet is the slide. We have the TT version ... absolutely love it. Living room nice and BIG, Bedroom roomy, bathroom ... big enough a guy can sit on the "throne" and actually be comfortable!
These are just examples to consider, but the thing that makes these 2 so special is all the windows on both sides and the back in the living room.
FYI: Our Outback TT came with the free standing table and chairs. We removed 2 chairs and turned the table. Works perfect for 2 people!
