    As ive said before you arent trying to run the Daytona 500 while pulling a trailer. The 6.5 is plenty of power, but i do believe it does need the 2.5 crossover, 3" downpipe, 4" exhaust, remote pmd with cooler, and probably an intercooler. Getting the air intake to suck in cool outside air instead of hot underhood air would be a big help too. The exhaust will help keep the EGTs down thus providing a longer lasting more reliable engine. The cool air intake and intercooler should help that too. Otherwise, the 6.5 is all you need for an actual pickup (1ton or less). Beyond that you probably need more, but then you dont need to be using a pickup truck engine. My 6.5 is at 225k and counting. It uses very little oil, i put a quart in every month or so. It is totally unmodified and it has seen alot of trailer pulling. It does well. Cant complain about it at all.

    The 6.5 is plenty capable of that. No it wont be fast but as i stated before you arent trying to run the daytona 500. You have no business pulling something that heavy that fast anyways and with a pickup especially. Id never ever buy a cummins (mainly because of the noise and the truck that they are put in) and the powerstroke doesnt have that great of a rep either. Ill take a 6.5 or a duramax, tho. A 6.5 dressed up with everything would take an unmodified cummins and rip it apart. Now, not saying the 6.5 would take that abuse long, not a factory one, but it could do it.The main problem might be more in the drivetraine than the engine. The cummins wont last any longer than the 6.5 or with any less problems and its much more expensive to work on. Been there done that seen that. Not worth the cost or listening to that obnoxious noise. If i wanted to drive a tractor, ill get myself a john deer, thanks. Have seen 6.5s with nearly 400k still going. Will stick to my chevrolet and 6.5 with its mellow tone thats nearly silent inside Not that i mind the sound of a diesel but the cummins is too loud, and too expensive and the truck they come in isnt worth a damn. Put that in your pipe and smoke it.

    one of my buddies has a 2000 1 ton dually with the 6.5 and he pulls a 42ft stock trailer loaded with hawgs...his cummins wont do it....alls that happens in the cummins is the torque converter slips and he dont move....ask any cummins guy who pulls any thing bet they arent on the first torque converter

    The 6.5 is what it is.. Great pickup motor for a pickup that you want good economy and power and want to pull a camper occasionally with......

    That said, NO, I will probably NEVER buy a 6.5......

    It's cummins for me....... Not that I'm real impressed with the Dodge trucks, but the cummins or 7.3 IH is the only real Heavy duty diesel engine you can get stock in a pickup... You can't call an aluminum block diesel heavy or duty at all, especially not together........ And the 6.5 wasn't either, steel block or not..........

    I agree with garth. I am not a big supporter of the aluminum heads on the d-max but i would certainly buy the dmax before any of the others. No cumaparts or powerchokes for me. However, the 6.5 is all i need. The only reason id ever get anything different is if i decided to get a pickup instead of a suburban. Dont really see that happening tho. Even then id probably not end up with a new truck and so it'd be right back to the 6.5. I enjoy not having car payments way way too much lol.

    I just like GM's a lot. I got my truck about a month ago so I havent run into any problems. I did research and I hope I never get stranded. So far I love my truck but man is it slow!

    The more friends I have that have them. The less I think they are better. I think there are more cam sensor failures on the powerstroke than there ever was of the PMD. Snap-on dealer had a 1998 cummins. In 125,000 miles it blew a head gasket and the injection pump went out, and then they found the lift pump went bad and that was what killed the injection pump. Expensive. The auto trannys the dodge and ford are crap up until the last few years. I put a cam sensor in a cust. truck today(2001 F250), and I am pretty sure my truck would smoke it. I was not impressed at all with the power. It was all stock but I was expecting more power than what it had.
