Hi guys. Newby here. I am very intrigued in regards to the 28 foot Aspen catamaran with the Proa hull. It seems to be economical to run and having a single diesel would mean only one engine to maintain, at least from what I have read. I am approaching retirement and had the intention of buying an F550 Ford truck and having a double or triple slide "T/C slide-in" on the rear. Somewhat like the Patriots Bill Belichik who loves to have players that can play more than one position, I got to thinking, why not put the T/C on the hull. O.K. why??? #1.The campers are insulated. #2 When you have the slides , you can open up the interior to between 10 and 11.5 feet. That being said, I absolutely would prefer to have that hull made in "aluminum". When I travel to the Pacific Northwest, there is considerably more obstacles in the water from what I have read and aluminum seems to be rather popular there. A bit stronger than fiberglass. Again, all this is from what I have read. Constantly learning. Also, being that the camper can be taken off the boat, I can put it on the truck if I wanted to. Maybe you can understand what I meant about the Patriots. Anyway, I would really appreciate any and all responses from you guys. Thank-You. Louie
