Howdy, I have a Fuzion 371 TH with 1.5 baths, 110ga fresh, 88 black and 44 grey.
I have been full time in it for 2 years (5 years in a conventional fifth wheel).
18cf fridge, w/d and a 700w solar system charging about 500ah of batteries to run everything but the a/c.
The kitchen is perfect for me. The residential main bathroom was a selling point.
The garage (second bedroom) has its own half bath, table and big screen TV. 2 double size beds that convert to benches, the ramp/patio is a great extension of the living area.
I chose this size (39.5') to stay with 2 axles. Any bigger and gets a third axle and more maintenance.
I hope this helps you.
