I’ve got a 2023 Chevy 6.6 gasser. I got after my 6.7 diesel kept being such a headache it wasn’t worth it anymore.
I have a 34 ft 5th wheel that weighs 10k dry and about 12k loaded. The Chevy pulls it just fine. Avg mpg flat ground (beach and back about 500 miles) was 8.9 hand calculated. Last mountain trip I took about 250 miles round trip avg mpg was 7.4.
It will pull that trailer at 70mph all day long in flat land. Definitely has to wind up the RPM climbing steep grades but it will maintain 55 mph.
