Forest River Catalyst, anyone have any experience?

I was looking at others, but hey have next to nothing for cargo weight. If I went on a trip and didn't want to drive another truck to tow a car, or drive the car, I would want something like the Cat., my hot rod weighs 4k and is 16' long., but kills my Ram on mileage. Plus, it's fun to drive. I don't need a bunch of bunks as its just me and the DW. But, it needs to be large enough to keep us off of each others necks:) however, I don't see a lot of insulation in the W-P's.
