Towing up canyons

I'm shopping for a fifth wheel and I'm probably going to end up with a loaded trailer at 16,500 #'s (pulling double). My truck is a F350 W/3.55 rear drive. What speed can I expect to pull up a 6% canyon like Parleys out of Salt Lake?

You may want to look into re gearing to 3.73's if you are going to be pulling 16.5k often. I don't think you will have trouble doing 55+ Up parleys. If you want to play it safe get an edge CTS to monitor your vitals.

I wouldn't think you would have to re-gear. Just lock out sixth if need be.

I'd guess you will be at about 50 mph in fourth gear, maybe less. I've never pulled anything close to that heavy with this truck though.

If you lock it out of OD, you should be able to do 55 or so.

I have not had to lock out. The truck picks the right gear to stay in the right RPMs for the power needed.

It doesn't matter if its Trappers loop by Ogden, Parleys, Daniels, or Logan canyon, The tranny will downshift to keep the engine in the powerband. Some grades you will not ascend at 70 mph. But I have found if I can keep my speed up and not get caught behind a slow mover, that I can usually stay pretty close to the speed limits. At least with my 13,000lb trailer.

WOW, I guess I need to swap for a 6.7.

When I pull my double rig, 16K 5er(rated at 16K but usually weighs in at 17.5 or 18) and a 4wd Rocky behind, up the 6-8% grades in Colorado, I hit them at 70 then slowly work my way down to 3rd gear hoping to hold 30-40mph as I top out. Straight piped(magnaflow glass pack) no CAT with a tuner!! And 4.10 gears

Yeah, these trucks are awesome. My 6.7 with 3.55's out tows my Bro in-laws 6.0 with 4.10's all day long.
