Wow!, have you come to the right place. Just read through the many pages of the forum pertaining to the unit model you're interested in buying. You'll find friendly folks and more answers than you might imagine. Good luck, and make several shows. Walk around, pick up brochures, disregard ANY pricing(all subject to change until the contract is done), then sit back with a critical checklist to compare options and standards. That will keep you busy for several weeks and lots more questions. When you're comfortable with the information, go to the Bighorn dealer and get what you want.
