Ok, I bought a 38 foot 5th wheel that weighs in at 13,000lbs and I will be towing it from Elkhart,Indiana to Canton, Georgia! I have the Smarty Jr. with EGR deletes and 5" Turbo back on the truck. Any words of wisdom for a 1st time haul with this kind of weight? Smarty setting will be Level2 on the Jr. with Tq default and timing Default. I pulled about 6000 lbs this way and everything felt fine! Any and all input would be great!
