Hi, I'm new to this forum stuff and need some help. I have a 2015 ram 1500 3.6l and recently bought a camper. the campers dry weight is 2200lbs, so It shouldn't have any difficulty pulling it. However It has extreme difficulty pulling it up the smallest of hills, and is even making the trans temp reach up to 215. Does anyone have any suggestions to elevate the stress on the engine/transmission? I have been thinking engine swap but I just don't know enough.
