I've been looking at the same possibilities, complicated by my Rockwood dealer recently going out of business, my Flagstaff dealer not carrying folders because the franchise would impinge another dealer's territory, and the Jayco (folders made for them by Starcraft) not wanting to stock any folders because they don't sell well here.
Dealer told me, when they were trying to clear 2010 inventory in spring 2012, that prices of Pups just got too close to that of comparably equipped lightweight TTs, and our long hot summers make buyers wary of buying a tent for almost the price of a hard side trailer. Hard side A-frame might find its own market, but that will be different from the family market that had been buying tent trailers when they were still less expensive than TTs.
I looked at the Jayco at the factory showroom going through in June, was unimpressed with fit and finish of an early production example of the A-frame model, and didn't like A/C choice nor installation. Starcraft brochures list different equipment but I have to see it to be sure, since brochures have the anything can change disclaimer. I'm inclined toward Flagstaff/Rockwood twins but I'm probably going to need to travel 300-400 miles RT to look at one now.
