This is currantly how the truck sits.It has 290K on the cummings 24 valve.It is backed by a rebuilt NV4500 and 4.10 gears in the rear.It is a puller, which is why it was purchased. To pull the 24ft camper and the 18ft car hauler and just about anything that needs to be hooked to the receiver.It is serving our family well as we have had it for 3 or 4 years now and around 30k.The only mods done to the truck are an edge tuner and a K&N air filter.And countless additions that I Call perttys. Like the camper shell, side steps and the grill gaurd.
