Good afternoon Everyone,
We are looking at a 2015 GMC Sierra 3500HD Denali, Duramax/Allison set up, with the option of dual alternators, 150 and 220 amp. Would it be worth it to get this option, and how much does your trailer actually draw from your truck when hooked up? I know you will just run some of the basic things, so I wasn't sure if the dual setup was necessary? We are new to this size of a trailer with this many bells and whistles, so I don't know how much it will draw when it's hooked to the truck. Also, can the trailer's batteries be charged by your trucks alternator(s) (with direct wiring, I would assume) Any info is appreciated! Thanks!
