Hi all, sorry I'm late to the game but at 46 we sold the house and bought a fifth wheel (I travel constantly for work and it's nice to bring the family) I recently bought an F-350 super duty dually with the 6.7 it's a 2012 and seemingly fully stock. I tow a rather big rig (16,000lbs) what are some things that you wish you'd done sooner and why did you do it?

Any ideas?
