1996, 34 footer with tag axle, 460 engine...Seattle to LA, up both sides of the Grapevine, and all the hills and passes on I-5, dropped down to 40 mph.

A couple of times had to go a little slower because a big rig in front of us was going slower, but the traffic in the next lane left was going too fast. So, we just kicked back, turned up the music, and rolled along...

We have the E4OD transmission. Just turn off the OD when going downhill, and judicious use of the brakes kept everything under control.

Tow/Haul mode uses all of the gears. It simply makes the upshifts crisper (lets the engine build more revs) and when the throttle is closed wants to shift down if it feels the vehicle accelerating.

Going down a steep hill it will select the lowest gear it can. If the rpms build to a point where the engine will over-rev it will shift up a gear.

At least that is how my 05 works.

Tow/Haul came in around 2004 and newer. Nice feature wit auto downshift to control downhill speed.

Before that "Over Drive Off" was in the end of the shift handle. It turned off OD ( 4 th gear ) and nothing else. If you need more engine braking, you need to put shifter in 2 nd gear.

I own a coach built on a F-53 chassis. Just went from Florida to South Dakota and back. Purposely drove through as many mountains as possible, just for the view. Mountain driving is a non issue with the Ford powertrain.

Yep - F53 chassis with a V10 is great. Just went coast to coast and back with our Thor 38' to include through Cody, WY into Yellowstone. Never a problem. You can read our post.

The only comment I'd add is if you have a toad, buy something like a BrakeBuddy. It will apply the brakes in the toad to help with the steep downhills. We originally had an AutoStop -as I've said the should call it AutoJunk - just didn't help on the long downhill slopes. Bought the BrakeBuddy Classic. Great decision.

Just our 2 cents.

Gas no problem!

Just drove our 31 ft Sunstar (Ford F-53 v-10) from west Ga to Anchorage and Valdez AK -and from there to Lakeland, FL, then back to West GA.

Towed our Ford Focus on a dolly all the way +/- 12000 miles. Hit plenty of long steep grades, at least two were 10%, and more 6,7 8 and a few nines than I can count. Had plenty of power and with the tow/haul mode I rarely ever touched the brakes- even towing the toad. Averaged overall 7.2 mpg.

When we first got the moho, I laid awake at night worrying about my first trip up and down Mt Eagle, TN. Now I know I can handle most anything in north America. Mt Eagle --- easy peasy.
