Welcome, Bill!
If you're looking for 6'6" of interior headroom and/or length in the bed,
Scamp is probably not for you, sadly. Interior headroom is about 6'2", and the beds, which go crossways between the walls, are about 6'3" or 6'4".
There aren't many molded
fiberglass trailers that tall. One that comes close is
Parkliner, built in North Carolina.
EggCamper is another, but they are no longer being made, and most are all-electric.
Best wishes in your retirement!
