Thread: Found a truck to pull my boat with.

What gears did they have? This one has a 6 speed Allison with top gearing of 0.61 and rearend is 5.13. Motor is at 2100 RPMS at 70 MPH or close to it.

I don't remember for sure but different than yours. Same tranny but we ran 22.5 low pro tires and looks like your running a smaller tire. Are yours the 19.5? Probably the same effective revs per mile. 2100 is right where that engine builds it's Peak Torque so your best cruise speed is going to be between 60-70.

Its beating my 2500HD on MPG. Filled the tank I'm running off of and its getting 24.9 MPG the last three days. And that is figuring it by hand. Hooked it up to the camper a few minutes ago and will have to drop the B&W 5th wheel hitch 2". Will use it until were back from Pickwick and Grenada then put the air ride hitch on the truck

Hooked up and ready to go. Should have been fishing today.

Sure matches the trailer well.

That's a pretty rig, Explain how the air ride hitch works please.

Heck of a nice rig you got there.

Very nice!!
