I just towed my 15,000 lb RV 5th wheel from Tennessee to Florida. I have a 2020 3500 DRW Silverado diesel. I used the Trailering Option and set my Trailer Gain to 6.0. 7 Pin plus connects my installed truck brake controller to my RV brakes (drum). I drove 60-65 mph and all was fine, even had rain and storms. Hope this helps Benny. I did need the manual option of shifting to L and adjusting the + - on the Shifter. Benny

Just bought 2020 3500 DRW diesel to pull my RV. I had "shimy/shake" vibration from day one. Came with Michelin tires. Turned out the truck needed two tires rebalanced (one big time), tires needed inflated to specs, and front end alignment. Took two trips to the dealer. Came off the delivery truck like that. You'd think for $70K you might get some QA at the GM factory. Currently have door ajar light on, driver cannot roll windows down, interior dome lights don't come on when door opened. Window lock not working. Going to have dealer also look at this Friday. No doubt a window motor, harness issue, body modulator or something. If Toyota made these type of heavy trucks, I would not think twice about buying one. GM is not too big to fail as far as I'm concerned. Keep it up GM and go out of business. Last one to leave in Flint Mich. be sure to turn the lights out.
