Our creaky old Cummins powered truck (bought used) seats 4, does about 20-23mpg bobtail and 12mpg towing a 5th wheel trailer at 22,999lbs. It's mileage is somewhere in between hauling a camper and/or towing smaller trailers. 1500 rpm to 2100 rpm in road gear. 1500 rpm to 2300 rpm in climbing gears. It's happy as can be hauling 1-1/2 tons in the bed when necessary.
Nothing I'd like better than to replace it when the time comes with a quiet gas engine truck that will haul 1-1/2 tons, or tow the 5th wheel at 22,999lbs etc and deliver the equivalent $/mile fuel economy in gasoline dollars. I would like it to maintain the hp I paid for at 5000-7000 ft. and not be too frantic in the rpm department every time it sees a hill coming.
Anything coming on the market that will fit the bill?
My first creaky old Cummins Ram was rated to tow only 6500 lbs. My second Cummins Ram with 4.10 and NV4500 was rated to tow 14300. 3rd was rated to two 9700 lbs. Fourth was rated to tow 13000. They all gave 19~highway, 18.5~ city and 10.5~ towing. My first one was a full 5mph fast on the speedo at 65mph. I was actually only doing 60mph wondering why everyone else was going so fast. Mileage was probably calculated a bit optimistic too as a result.
High altitude power loss is a reality with a N/A engine gas or diesel. Frantic at the thought of a downshift is entirely optional.
Why are you thinking new truck? Diesels, especially Cummins Rams, last well over a million miles with only minor repairs.:B
