I have used a 98 Dodge Ram 1500 with the 318 for the past 2 1/2 years. It has been very reliable with just enough power to keep up with traffic without flooring the gas at every intersection. But now I want an enclosed trailer, and since I now believe in getting the biggest of everything I want at least a 20 ft trailer maybe a 24 ft. Now my questions would my truck be able to pull this as is with no performance upgrades? I doubt it. Would a cat-back system help much? Would a new performance chip help much? Headers? New gears in the rear? Would these lessen the life of the engine or transmission? Would they help or hurt with mileage? As you can tell I don't know much about any of this stuff. Also could I put in the chip, or cat-back myself? If you have any suggestions either post them here or email me at Barkleymut@aol.com. Thanks a lot guys.
