That's the bad thing about steep downgrades in a heavy rain. They recommend that you use extreme caution with an exhaust or Jacob's brake. Some recommend that you don't use them at all.

On the Coquihalla Hwy through the Rockies East of Vancouver, 6% grades are unfortunately fairly common, with the climb to the summit being 8%. Fortunately it was a dry day when we came down. Hwy #3, which is another option through the Rockies also has numerous 6 & 7% grades. These grades are as posted on the Hwy signs.

I have not experienced any of these steep grades yet. How did your Ford do coming down and what is your strategy starting at the top? Do you start down at a very low speed and hit the brakes ocassionally or downshift and let the integrated exhaust brake keep you at a reasonable speed?

The trucks do a good job holding the rigs back in the normal auto trailer towing mode. I was traveling down a few 7 percent grades 15 miles long in the rockies and then I put the tranny in manual mode and kept the rpms where I wanted them.

On the 6% grades I shifted down to 3000 RPM and the truck maintained a constant speed of 55 - 60 mph, didn't have to touch the brakes.

On the 8% I slowed down to about 40 - 45mph and shifted down, had to use the brakes a couple of times. Next time I will use manual, but didn't want to try it this time, as the gear indicator on the display currently doesn't work. I was using the Tachometer only.

At the top of the 8% it was a bit nervy, as DW distracted me to open the rear window & something else, but once I downshifted and under control it felt OK. Knuckles were a wee bit white till I got to the bottom.

I have been up and down route 3 several times it sure will test out any truck. There is a route just outside Castlegar that is 12% and all switchbacks, what a hairy ride that is. Even with my truck pumping out 400 hp it sure made her grunt. With all the switchbacks you just can't get any run ons for the next pull. You got to keep an eye on the EGT's, you can literally melt these new diesels, they run very hot to start with and a hard pull like the number 3 the EGT's can get out of hand very quickly.
Being in the far west if we head east we have to go through Golde/Rodgers pass or the #3 and if we go south we have to go through Grants pass, seem like there is lots and lots of mountain ranges no matter where we go

Not an issue for me - I don't have either

Mine is almost an antique truck compared to all the folks with the 6.7, but on the Colorado side of I-70 it does like to run away a bit on the downhill side. I try to not ever let it run over 3,500 rpm, and if it does, I use a hard brake to bring it back down to where I like it, rather than a slow drag on the brakes that cause heat. I have to say this is the heaviest rig I have towed by quite a bit, and these disk brakes make it childs play.

Dan - On Hwy # 3 I bypassed the Creston to Castlegar stretch, which I believe has the 12% grade. At Creston I headed up Kootenay Lake and came over on the ferry, then down through Nelson to Castlegar. Probably takes an extra couple of hours, but it was a good mostly level road. I'll take this detour again if using Hwy # 3.

Coming West, the hill down into Osoyoos was white knuckle.

Last time I came down the hill into Osoyoos my wife had her hand on the door handle ready to jump

there was a big truck with red hot brakes coming down behind us

Oh Boy... I sure miss all this being in Ontario now... The road coming out of or into Golden was always fun even without a 43 foot trailer on the back. Plan to travel out west to Calgary and Kelowna with our unit next year. Guess I better start planning routes.

Oriana · 10-08-2013, 12:35 AM

Brad - you're probably thinking of the climb out of Golden heading East. They have done some recent work widening the road, but some corners are still tight.

I hear you! I wasn't a Ford fan either, but then my friend got a Ford Chassis Cab F450 XL and I was impressed. It seemed tough, handled well, and they raved about it. So, three years ago, I took a leap and got my own F450 XL. Best decision ever!

It's been rock solid for me. Hauls anything I throw at it, comfortable on long trips, and surprisingly quiet inside. Sure, I had a minor brake issue once, but hey, even I mess up sometimes!

Sounds like you found a winner with your F350 too. Who knows, maybe Ford has surprised both of us
