Car towing system for my new Class A

To all Thanks for all the great information. First I like the idea of going to Roadmaster for that deal except I'm in Massachusetts and that would mean I need to tow my car out there first. As for the weight of my car it's a lite weight about 3800#'s. Car is fine for towing all 4 down being a drive by wire car it has a simple electronic disconnect to tow which I guess is nice. I can see weighting some of the items to figure out the weight but I'm not sure I have a place around here that could weight it loaded... Don't know of any weight stations or places near where I live in Tyngsboro, Ma right next to the NH border. If anyone has a suggestion,As for the installation I went over the entire process. Being quiet capable of tackling most task at home, car and work I figured how hard can it be and though it's not disconnecting many electrical connections he does require a disassembly of the frt end, lites and a fairly decent amount of cutting to fit things in there. Like the Hyundai person said if there's no issues ur fine, but if it falls around what u touched the dealer will fight u tooth and nail blaming someone else and if there is on a car like mine can be disastrous with so much electronics it makes Best Buy look bad... so I guess it's a call I have to think about after I view all the options so keep them coming please. :-) Thanks everyone...
