I'd love to have a 14' box PUP like yours. When we bought ours, the dealer had a 14' dual axle Jayco for sale, too, for just $2-3k more than our 1007. We really wanted it, but realized quickly that our minivan couldn't handle it, so the small difference in price needed to be increased by the price of a tow vehicle.
Our TV is now nearly years older, and this is probably its last year towing. We're seriously thinking of buying a mid-sized truck like a Dakota and upgrading our 1007 PUP to a 12' or 14'.
