Cummins diesel and 16' Scamp.

   I would hate to get rid of my 2018 Ram 2500 diesel to pull a 2000 lb trailer, 342 axle ratio. The truck gets over 25 mpg empty at 60mph with no wind or hills. We found the 32 5th wheel to be cumbersome in tight turns on dirt roads and the overall driving experience through towns and forest campgrounds and lucky to get 12 average mpg doing that. Gas being what it is, we don't want to give up camping. Any guess what our mpg would be under ideal conditions with the diesel? Granted steep hills and headwinds will make a difference, but I'm thinking the low profile and light weight would yield close to twenty mpg with a low of 15. Your thoughts?

I had a 1993 Dodge 2500 with the Cummins Engine for over 20 years. This truck had a standard transmission and mechanical fuel system. It would get about 23 mpg with no trailer. I often pulled trailers up to 10,000 lbs. (The max rating for that truck). My monthly fuel reports never averaged below 20 mpg. The lowest I ever got was 13 mpg on one tank of fuel. (I think there was something wrong with the fuel!) Other than that the lowest I got on any fill up was 17 to 18 mpg.  I don't think your 2018 truck will know it's pulling a trailer with the Scamp 5er. The newer computer controlled engines should get a little better fuel mileage than the '93. You should get 20+ most of the time pulling the Scamp.
