Wondered why I didn't see that one, then realized we'd started out talking FW and this one's a Chateau. We're moving up the food chain model wise.
On the chassis, it seems the Chevy is always a 4500 which is closer to E450 than the E350 offered in these RV sizes. As satisfied as I am with our Ford, the Chevy being a "45" series sets it clearly above the E350 alternative.
On Chateau, I like the "full wall slide" a lot. Also the way the Slide does NOT include things like Appliances and Plumbing. That concept makes me nervous. Wish it didn't use a shower curtain instead of a hard enclosure. But I can see that if it had a door, there'd be no getting in there. Our shower is a folding "door" and our bedroom "door" is also one of those. Since our A/C isn't ducted, we never close that. Rather, we block rear from front with the bathroom door or one of the closet doors. DW has to have a Pantry, and all the ones we're discussing have that. Split level floor might take the Thor units off the table though.
Another thing to consider is this: IF the Floor is high enough to provide decent outdoor compartments, the corresponding interior height means that people seated inside can't see out the windshield either underway or parked. We ruled out some Winnebago models because of that. The view forward in a 29B, was the edge of the cabover mattress.
All this means, we have to try to visualize how we'll travel, camp, eat, sleep, LIVE in the thing.
