1/2MillionMile6.0

No. The engine has been replaced once and the transmission twice. The fist motor went 350k. The truck drives nice and tight, straight, and handles very good. I recently had to replace the AC system. It spends its whole life towing basically. If I could figure out how to post some pics I would, but this forum is strange to me. I spend all my time over on NC4x4.com, I wound up here cause I’m thinking of buying a 26’ Gooseneck trailer that I can just leave my camper on the front of and pull the Jeep on. But I fear it may be too much for this truck to haul across the mountains, but I may try it anyway. Then I’ll just explain to the wife “looks like I gotta buy a bigger truck”

Some curious reading lead me here. Wondering if the original poster ever found an issue or if he is now happy with the truck. I currently own an 04’ 2500HD CCLB with the 6.0 and 4.10 gears. I tow my rock crawler on a double axle trailer weighing about 7k and also have a slide in camper in the bed that weighs 1200lbs. The truck does amazing. Granted, it drinks the fuel at 7.5mpg, but it’s also paid for. Did I mention it has over 530k miles on it?? I just wanted to echo again that these motors are not going to pull a grade or hold speed on even a small hill in the 2500rpm range. You are not going to hurt them by revving it hard, they’re made to do it. I go on trips once a month which are 4-7 hours from home and always having to cross mountains. Couple grades I pull are 5-7 miles long and I usually climb them at 3500-4000 rpms and have held it at 5000 a few times as well. It’s not a diesel, they make all their power up above 3500. Don’t be afraid to let it eat!!
