There are lots of 5ers available with an overall height of 12'6", even 13' which give pretty good bedroom height. Not many humans are 6'5" so rigs are not built to suit that height.
How much time does one spend standing in a bedroom? My Alpenlite must have over 6' bedroom clearance but I would be happy if it was less than the 12'6" exterior height to avoid some of the low branches in CG & reduce sideways windage.
Pricewise, if you want a good quality lightly used 5er better be prepared to pay more than $30,000.
