The Superglide is a great investment if you have a short bed truck. You'll be glad you bought it. As others have said, download the PDI checklist here and use it to inspect the RV BEFORE the delivery date. That way you can give the dealer a "fix it" list to be accomplished BEFORE delivery. Until you hand over the check YOU have the power ... after ... you have to rely on their service commitment to get your issues resolved. We gave our dealer 2 things to fix and they were not done when we went to take delivery ... we almost walked away from the deal.
You are making a HUGE investment ... may I suggest an electrical management system (EMS) by Progressive Industries? You can go either hard wired or portable. Whatever you think will work best for you. You are paying big $$$$ for your RV ... this is relatively cheap protection.
Whatever you do, enjoy your new Montana and use it every chance you get. Welcome to the forum!
