We upgraded from a 17'
Casita to a 17'
Bigfoot -- actually 17.5 feet. Reason: BF is 1 foot wider than
Casita 17' and gave us the floor space we need to navigate around our 2 large dogs at night. And now we have a sofa for snoozing on in the daytime. This was just the right move for us. The difference in space is quite remarkable.
Regarding the "cute factor," I don't believe
Bigfoot has it; whereas
scamp,
casita,
burro,
trillium all do. No one stops us at restaurants and gas stations any more asking to take a peek inside. So many did with the casita, I "sold" 4 of them in 2 years (having folks purchase new from the factory after touring my trailer). Possibly in part because of the lack of the "egg shape" in BF (curved sides vs squared sides).
As for the cost factor of BF vs
scamp and casita -- you can find a bargain in used trailers if you're persistent and willing to wait. We did!
