Actually Overland you bring up a very interesting point. There is clearly a sweet spot for a well built camper hitting around the $40K mark.
There are many in this forum who were former Casita owners who bellied up to the bar and have plunked down a significant chunk of change for the Ollie. While the Ollie may have a ~40K base price, it's not difficult to get a sticker price of over $60K when you drive off the lot.
As a former Airstream owner, our 2007 unit was a great unit...it was 25', full sized fridge, and could sleep up to 6. (And it was around the $60K mark). With that being said, we've seriously considered an Ollie for the better part of the year, but the cost and the differences between Airstream and Ollie have delayed our decision. Personally I would have bought an Ollie a long time ago if a) the price had be lower or b) the trailer would have been larger.
Ollie is one of the best built campers in the market. No question...But you pay top dollar for that.
Just one man's opinion...and no, I don't think AS is the dark side...both trailers have a place in the market...
