We have a 36' Toy Hauler that empty is 11,500, but loaded minimally will be 13.5-14K lbs that needs to get to Alaska. Wife LOVES this truck, and I wish it would catch fire in the middle of the night, but it's not the hill I want to die on.... If it were up to me, we would be in a 2014-15 6.7 time meow, but she owes 10k on this turd, so......
2006 F250 KR CCSB 4x4
Motor blew @ 212k miles, currently has 225K, 13K being on newly "Bulletproofed" EGR
deleted block. Tranny is original. Had a tune before it blew, but her dad made the shop delete it when they rebuilt the engine (biggest reason she doesn't want to dump it, daddy dropped $12K on it)
Just hauling the camper from Nashville to Clarksville, on 3-4% grade for a few miles, and flat after, this thing is a struggle-bus. I installed airbags, and it stops fine, but it lacks umph. The truck would "stutter" when cruising in tow/haul. It acted like it wanted to shift and would jump 100-200 RPM and go back down every 30 seconds or so unless I was accelerating. IDK if the torque converter was trying to engage or not. I may have just been cruising on the brink of a shift point and not known it, but I don't even remember what the RPM's were now.
