Yep. I really like the fiberglass RVs. There is a youtuber which does a great job on this link,

I would be up for something like a Casita if it packed in the 3500 pound carry capacity, 60 fresh, 42 gray, 42 black, separate 6 cubic ft freezer/fridge, and oven. Also, much of the reason I want the 3500 carry capacity is to carry auxiliary water and fuel, and about 500 AH of batteries for extended boon docking. I don't think items like auxiliary tanks could be mounted on the bottom of a fiberglass RV.
