1st consideration is the wheelbase to length ratio. If it's less than 55% it won't handle well - period, and can't be made to. All manufacturers make several "grades" of MH. The shorter ones tend to be "recreational" price point - and construction quality. Suitable for weekends and vacations. Not so good for extended use: snowbird or full time. One A/C is a noise problem. With two you can run front when occupying the rear and vice versa. When it's really hot two are available. Our single air also cycles one degree above and below the setpoint. We are too cold or too hot 2/3 of the time.
The engineers and management at Winnebago mostly have zero experience as RV'ers. It shows! In my opinion quality of construction of larger gassers is pretty similar. Go for the floor plan. Appliances are identical third party sourced. Not sure whether it's that folks who pay 500k up are pickier, or that the bling creates greater construction and maintenance issues, but they seem to require a lot of shop time.
This is my 53rd year as an RV owner. Have owned the spectrum from camper to full time rigs. My experience is generally you get what you pay for - at any length. I've seen lemons at every level. And, if your out of town, under warranty, living in it full time, your black tank is full and the toilet valve fails plan on a DIY project!
