I'm 6'2" and pretty sure the Casita measurement is pretty accurate, and the "taller"
Scamp seems to be the same size as the Casita.
I think Parkliner didn't change the cabin shell size; the extra foot added to the new models is on the tongue, where batteries and tanks got crowded. Mine's a 2014, and is 82" wide at the bed, almost 78" high in the cabin, but a shade over 75" under the ceiling
light. Bath is probably 6'2" and a bit. The new ones have A/C on the roof (moved from the earlier side wall); it will protrude down, I'd guess about the same as my
light.
Many will wisely say that bed size is more important than ceiling height, but at a
rally, I found I really didn't enjoy even limited moving around under a ceiling with knobs and stuff sticking down, so for me, both were important.
I think in addition to those in Jeff's rundown, the bigger
Oliver is 6'7". And Lil Snoozy's design is all clean on the ceiling, which helps.
