I spent a enormous amount of time in my current Winnebago Minnie Winnie 31H and a Jayco Greyahwk 29MV.
In my opinion, structurally the Winnie had it over the Jayco. More metal, metal framing, wiring laid out in a way that made sense, fiberglass roof (but flat, what the hell is up w/ a flat roof nowadays?), etc.
From a touch and feel perspective, the Jayco had it all over the Winnie. The cabinets, cushions, countertops, added value items like the transfer switch and inverter, blah blah blah. The list of goodies goes on and on w/ the Jayco.
In the end, all that good stuff came with a stiff weight penalty. The Jayco only had 1600 pounds of OCCC and the Winnie had 2900. I went w/ the cargo capacity because in the end my motorhome is a vacation home, not a FT place. And I really don't want to stress about loading it - sorta defeats the purpose for me.
