Does not the 2009 F-350 have the Tow haul mode?? it works fine for us. Need the dually for carry capacity and the GCWR is in question. You may not have enough truck...to stay within spec,s..If that means anything to you....otherwise....it will pull it fine..

Many of the folks with DRV 36' RVs are pulling with the F450 dually, I am. The dually has more carrying capacity and gives you more stability.

Does your 2009 F350 have the towing package with the "Tow Haul" feature? If so the exhaust brake is not needed it would be redundant.

My F450 with "Tow Haul" has been through Vail Pass in Colorado and Teton Pass in Wyoming and a few other very steep grades with no problems. The "tow Haul" mode is basically an exhaust break.

The tow haul mode in my Dodge Ram just changes the shift points. The diesel exhaust brake is a whole separate mechanism.

I agree with a previous post, once you have a diesel brake you would never be without one.

Long downhill grades on the interstate without touching the brakes at all because the diesel brake is enough to keep you from becoming a runaway vehicle. How nice is that?

It saves wear and tear on the truck and trailer brakes and those brakes are still available and not overheated if they are needed in an emergency.

From an exhaust brake manufacturer rep - only need one if you travel through mts with long downhill stretches . Won't say which rep told my friend that when he wanted to buy one. We live in a relatively flat region.


Are you sure this person did not sell brake parts? An EB saves on service brakes. You know the old saying, once you go EB you'll never go back.

The only reason you need dual rear wheels is to haul additional weight over the rear axles and spend more money on tires. SRW will haul the 5er pin weight just fine. Look at the truck specs to compare the axle weight ratings. SRW is just as stable as DRW.

Check your weights on your camper and truck. If they are close or over then you need a dually. If your weights are ok or close to it then I won't stress about it.
Braking should be ok with your truck and trailer but I agree that you have to have it when you travel a lot of mountains.
I would suggest that you get all the numbers for the truck and trailer (take and get it physically weigh at a station, not just the numbers from the manufactorer). Then post it here and some of these guys/gals will have a hay day on helping you with them. It's what we do around here (help people).

I've got both a 6.7L diesel dually with a 8' box and a Jake-Brake and there is no way i'd do any serious travelling without both,now mind you we go south every winter now so i look at my rig as a required set-up for what i think as "safe travelling" which it to say my 6.7L Cummings has the torque to haul 16.000 LBS up the smokey mountains with ease and the Jake Brake to spare my brakes and help slow down on the way down. I find that having two rear tires adds tracking and stability with cross winds and in the event of a blow-out the extra wheel goes a long way to relieving anxiety and stress while travelling. All in all i consider my rig to be optimal for what i'm doing and i wouldn't change a thing.

I am guessing your 09 F350 has a Gross Combined Weight Rating of 23,000 lbs. I would also guess the truck and Mobile Suite will exceed the GCWR rating before you start adding additional weight with everything you're going to put in the 5th wheel.

This one doesn't smell right. Anyone who has actually owned and used an EB wouldn't be without one, mountains or not. I use mine constantly even without the trailer in tow. It drastically saves on the brakes and just makes driving more enjoyable.
As others have said, once you have one you'll never be without it again.

I am not sure you can put an exhaust brake on a 6.0,6.4 or 6.7 Ford ? Has anyone put an EB on these engines ?
