Anybody towing with a late model gasser?

With my old 6.0 the only time that I saw temps in the range that you are reporting was when the TC was going out... Never had an issue with the truck pulling 10k through Georgia area. To me it's about perception, engine running at 3-4k rpm is not screaming.... People always freak and think that the poor little engine is screaming... Lol...It's not, and it's not going to explode or drop a piston along the way. Running at that rpm is normal when it needs the TQ. Simple. So OP there are several running gas trucks pulling campers out here. Perception seems to be the biggest mind block that people have when it comes to pulling campers. I have stated that I have pulled campers with both. It's really up to what your willing to spend. For me...newer diesel, a big negative, why? All the potential cost and emissions that are present. Open the hood to a new diesel, and tell me how easy that engine will be in working on it, or how cheap it will be.... Older diesels are great without the emissions but.... Higher miles means more truck repairs. So the choice is urs, there are several options, if u go gas then go with the 4:10 gear, just a personal preference. New offerings of gas engines are looking really good. Despite GM keeping the 6.0 around for a while, I still like mine and don't complain about pulling the wieght. It really does well, its obviously a good engine to keep around for GM since it's darn near bullet proof. Anyway get what you want, but don't look past the newer gas choices if u want to stay simple and reliable. Btw just got back from fort wilderness and had the same conversation with a fellow camper.... Who is now switching back to gas due to some issues on his current truck. Ain't saying what brand or engine, no need to start another thread war ( probably another member here). Look at my sig, this is what I currently own and will be keeping for a long time. Previously had been a DMax and cummins not listed yet. Also to add the new dodge 6.4 is looking really good, should put a smile on a few faces around here. Good luck on your search.
