We are pretty new to the forum and our Heartland. We have had it for a week and are doing our personal touches on it now. Our first tow with it is in two weeks to St Augustine for a little beach camping trip.
i wanted to post up what we tow our Road Warrior 427 with. This is our 2016 Denali 3500 dually. I bought this one new and wanted to stay with the LML Duramax and not be a tester of the new L5B. She towed the coach home very well from the dealer and even with 3700lbs of pin weight the truck was still level as can be. I don't do sag. Lol.
The truck is still emissions compliant but I do have a Motor Ops tuner and use the heavy tow tune. After my first trip I can report back on tow mileage with this one. On my 12k V Cross fiver the best I got was 12.1 on a nice level tow but usually got got 11.2-11.5. Without the tune I got about 1mpg less towing and 2-3 mpg better unloaded.
