Hey everyone, just bought an 05 2500 Cummins. It’s got a catback s.s 6” exhaust with the cat off. Going to be using it for towing roofing trailers with a 8-12k load max. She came with a smarty so I was wondering what the best tow setting would be for this model, everything is stock except for some skytrackers on the front so I know I won’t be able to use most of the settings. Also don’t want to be rolling coal with a trailer on the back as it’s going to have the company name on it. Just want a little extra power to tow with, Thanks
