Am considering a particular unit and forgot one of the most imortant items. What type of suspension would a 38' cat 330 powered unit have and can a chip be inserted to up the power factor. Would Banks Pak help this unit in many cases of diesels it doen't factor in much to have Banks. Als would this have Independent front Suspension. Could a couch(Bed) be installed in place of the recliner chair. I know these are fine units but I have no experience in owning a Tiffin. Guess I'm just to cheap. If I purchase this, someone is going to get a really good 98 Pace Arrow 460 Banks Pac with 29K miles on it with W/D Sat and the works, including Tag Axle which I love and would be giving up on the Tiffin. Thanks
