I looked at a 2012 Jayco Recon 39c yesterday, super nice toy hauler! I have a 2007 F 350 CCLB, 4by4, 6.0 turbo diesel, DRW. I the 39c has a listed dry weight of 13,700. My truck weighs 9,300lbs with everything. the GCWR of my truck is 23,500. If i had the "tow Boss package" my GCWR would be 26,000. As far as i can tell, the only difference in my truck and one with the "tow Boss" package is the 4:30 rear gear. If i wanted to "upgrade" to a toy hauler of this size: would it be wise to change to a 4:30 rear gear? I would like a larger truck, either 450 or 550, but i only tow 6 times a year at the most.

Amother issue to be concerned with is the GVWR of the truck and how much payload caopacity yo have available for the trailer pin weight. Your trailer will have a loaded pin weight of over 2800#. Use 20% of the trailer GVWR.

Say the trailer has a GVWR of 16,000#...you will have a pin weight of 3200#.

Add the 9500# for the loaded truck to the 3200# and you have a loaded weight for the truck with the trailer of 12,500#. As long as you are good with a GVWr of over 12,500# you are good. I would not worry as much about the GCWR if you are only a little over.

But be sure and understand the weights and make sure you are comfortable with any overload conditions.

no problem, i got lots of room for pin weight! truck with one tank of diesel, and me in it weighed: front axle 4800, rear axle 3920. trucks gvwr is 13,000. those weights are with a toolbox and the fifth wheel hitch, just add family and another 37gal of diesel.
still think changing the rear gear to a 4:30 would help?

I just got a 2012 F350 Crewcab dually. 13,300# GVWR and 30,000# GCWR.

The 4.30 gear would help on the hills and not require quiet as much downshifting.

I think I would try it with stock gears and see how it does first.
