We have a Dutchmen Rubicon 2900 tow behind TH. It works great for the two of us. With that said it does have:
Dedicated vapor wall to separate the 10' garage from the living area (w/slide).
Separate bedroom with queen island bed (I hate having to crawl over DH to get out of bed).
All the usual heat/ac/8 cu ft. fridge (bigger than the normal 6 cu ft.); microwave/convection oven; full bathroom; on-board 4000 Onan (sp)generator.....
We do have a power awning which I (DW) find very handy when DH is away playing, or when the wind pick up at night!
We also have a fuel station, we haven't yet used, our toys are bikes & kayaks but this year we may bring the motorcycle!
We do have a Happijac bed system in the garage area which could be used for guests if needed, but it stores up toward the ceiling so it is not in the way of the toys in the garage. Ours has a couch as a lower "bed" so it is great for sitting and entertaining. Leave the bed up and bring down the couch...nice little extra!
We also have a large (I think it is 90+ gallon) fresh water tank and equally large (40+ gallon) grey and black tanks).
What it is missing is an oven, which I (DW) didn't think too much of, but after using the TH for a year - I do miss the oven!
DH did not want to give up the space in the bed of the truck, nor go for the expense of a 5'er hitch - so we decided on a tow behind!
There are a lot of TH out there without the dedicated wall so keep looking to you find what you want/need.
