We travel frequently with a couple who own a Platinum. The body is built like a tank, but shaped like a ball....less usable space than more square shaped units. Ya, it looks more streamlined, but our fuel burn is always close either way.
As DocJ said the cabinets are junk, latches and hinges just don't hold in partical board, the plastic laminate comes loose where ever it sees moisture.
I'd look at Lazy Daze & Born Free if it were me buying.
