I agree its an expensive option, but we also have dogs which its nice to bring them along. we stayed at the lodge in yellow stone last year, and the DW really felt like we missed being part of the experience by staying in the lodge vs a camper.
I am torn on the two, the leprechaun gives more space and better seating, but sunseeker may be a bit easier to maintain. they look to be sitting about the same price. So basically a space / layout vs maintenance question.
I don't have indoor storage this and live in Wisconsin, so need to deal with winter, which makes me lean toward the fiberglass roof based units.
