Crummy fuel economy
I towed a tag trailer 450 km down the highway at 55-60 mph and got 37 liters/100 km. (6.4 mpg). Can you get a Dodge or GM to go through that much fuel?

Did you ever pull your '07 MS with your 2015 Ram? I'm curious as to how much more power it takes to pull a 29000 lb RV vs a 20k lb unit?
I did but not any real distance. The 07 scaled about 19k and 11 truck about 10k. I documented speeds on certain grades. The 15 is about 10 and 16 Rv is 23k. Some grades the 11 performed better like thre the Syskious in northern CA. In eastern wa west bound 90 on Vantage pass the 15 did better. 11 had 3.42 with basically same rpm as the 15 with 4.10 running one gear lower. 11 was 350hp 15 is 385.
