We have a Wildcat 327ck and it has most of your wish list wants. I took a plant tour in august and saw how they were made.
They start with a new design drop frame with a Mor Ryde suspension system and Load range E 16" tires.
The walls are vacuum bonded foam and 16" spaced ribs with fiberglass insulation in the roof.
The layout is great a large TV and fireplace on the end wall with a great view.
50 amp service prep'd for a second A/C, washer/dryer hook up, and solar power hook up.
Large FW, gray & black water tanks with a 10 gal. hot water heater.
Lots of storage and a wrap around kitchen with tons of counter space.
The PDI was great with a few minor problems due to shipping from the plant.
