Just sold my 2003 2500HD chevy, Gas motor. I just purchased my 5 th wheel last month , went out and put a hitch in the back, pulled my trailer to Jasper TX. With all 4 of us in the truck loaded down with supplys and food my truck struggled up the hills pulling my 32.5' 5 th wheel.So I just sold it Thursday. Now Iam looking to buy a used f250 but I hear bad things about the 6.0 . I once owned a 7.3 , I had no problems with it. I also like the Doge 2500 diesel. I found a few here in Houston TX. They run around 17 to 22k.with anywhere with 120k to 180k miles. Looking for any suggestions.
