[farmerhurd]

ok so i was in a pull a while ago , placed in top 5 out of 20, gonna be another pull local next month, i had and will have some serious competition , there are no rules other than 16" hitch height and driveshaft chain, im making a weight hanger for the front , traction bars and " custom bump stops" my truck =04 6.0 auto x-cab sb ,intake exhaust and sct, suggestions on how much weight and exactly where , traction bar length, and rear suspension travel limitations? 8600 lb homemade sled 16" hitch so there wont be much tounge weight on my truck, last time i lost to much heavier trucks. thanks folks, always a big help!
