Has as much floor space as an Aliner or Chalet so it would not be any more claustropobic then those. Don't know how tall you are but I can manage just fine. But in the final analysis the reason for going smaller is to sleep up off the ground and provide a shelter from the elements. If space is the major concern then maybe something like a 30' TT or 5th wheeler would be the route to go. Also, if towing size and weight are of the primary concern, then a popup camper outshines them all for interior space when opened up. AND ... I've not heard of (of course it may have happened), of a bear dragging someone out of a popup camper like I heard happening with a regular tent.
Dale, I'm sure your camper is perfect for you and I am definitely not knocking it. It wouldn't work for me because I am both tall and claustrophobic. Conversely, I've seen others in RV parks happily camping in rigs that look much like yours, but 1/2 the size. We all find the one that is right for us and rejoice in no longer sleeping in a tent --even as others think tenting is the only way to go.
