I'm not aware of any B+ units with the corner bed that work well for tall persons. That said, we have an Aspect 26A B+ with the corner bed. My wife sleeps on the inside and I sleep on the outside so I have more room for my feet (6' 3" +). Our bed does not angle on the outside edge like some so that helps.
Ford does have some issues with leg room. I fixed that on our unit by using a 2 inch square tube to raise the seat and move it back, lots of room for the seat to slide back with the slide in. Makes a world of difference. Better leg position and easier to move back and fourth from cab to coach area.
On the used market: Trail lite, Montclair, and Auguasta B+ units can be found with a Chevy chassis. Then there are Leisure Vans units and some other higher end products that also come with the Chevy chassis. Seems that more and more new units now have the Chevy chassis option.
Good luck on your search.
