I've finally put some miles on the Andersen hitch and its working fine for me. I have puma kf30bds and a ex cab 8'bed superduty. I know it's transferring weight as I can tighten the chains as its being hooked up and watch it pick the tongue jack up off the ground.
I was skeptical at first, but it's quiet, easy to hitch/unhitch, with no white knuckle experiences on the road. I'd buy another.
I have an 03 f250 ECLB with 3:73 gears. I tow a 2010 Puma 30kfbs. Before the tuning from Mike @ 5star the truck was "ok" but honestly felt like a drunken sailor was in control of the transmission.
After the tune the truck is a completely different animal. The transmission finally has some common sense.
@ the 59 mile marker on I 75 in KY there's a stretch of road referred to as "dive bomb hill" before the tune I'd top it at 58-63. After the tune I pulled the same hill @ 68 and was picking up speed. I'm confident if I pushed it I could've hit 70. Granted I was turning 4k rpm, I've been told to let the V10 eat and I've been plenty impressed by it.
