2003 ram 1500 tow rig

[superyota]

2003 ram 1500 2wd, all stock except for a daystar leveling kit and 33in. all terrains.  3.7L V6:yikes:and a 5 spd.  pulls my truck and trailer just great.  averaged about 14 the last trip to rubicon from bakersfield.  crusies just fine down the freeway when it's flat, but climbing grades becaomes interesting.  was thinking about gearing it, but i'm afraid it will looses it's cruising ability when not pulling a trailer.  my wife also uses it for pulling our two horse trailer and two horses.
