I know a couple who bought one of these a year or so ago. It's a pretty nice unit. The interior is a little bit "typical RV" to my tastes, but it was decent typical RV anyway.
They've taken quite a few trips in it and really love it. It has slide outs but you can mostly use it with them "un-slid" if you want/need to (it's a little hard to get around the side of the bed to the bathroom).
I wasn't thinking about its not being diesel, but I was more focused on the electricals. I wonder what the builder's reasons are for going with gas?
But hey, it's molded!
PS: I think it was just under $140k
