hi all i have A 01 2500 with a Auto & BHAF and thats it. I drive it evey day but i tow my rock crawler jeep to moab alot ( 8 hours way). i live in CO and i was looking at a 5" turbo back, fuel pump and an edeg with juice. i want to be able to tow will ease. I have to drive in the mountains to get to moab. any help would be great? also the truck has 160,000 on it. Any tranny up tips would be great. every thing runs great. just slow towing. 8 hours is alittle long to tow.
