Used 2011 F350 6.7. Do I need to purchase warranty?

[F5Pro]

Looking at used 2011 F350 power stroke crew cab to pull my travel trailer. Vehicle has 95k miles. What is the opinion of the forum as to the benefit of an extended warranty for this truck?
Okay. It is not a factory extended warranty. It is an aftermarket insurance policy that covers the turbo and the HPFP, but not the radiator. While I have enough money to buy an '11, I do not have enough to buy a '15-20 without going into debt, which I am trying to avoid.

Thank you for a straight answer.

I bought what I could afford. Any kind of exhaust brake is preferable to creeping down a mountain with a gas truck. I get antsy going over about 45 with my 7000lb trailer pushing me, so its downshift as necessary, run the engine up to about 5k rpm then use the service brakes to slow back down to 20 or so and repeat the process as necessary. Have I been misinformed by Ford and their towing guide about having an exhaust brake? Is it so crummy as to be worthless? Thanks

For the '11-'14 Super Duty's the exhaust brake is activated when you step on the brake when the tow/haul mode is on. The grade braking from the transmission and the exhaust brake on my '12 was satisfactory to me when we pulled our camper thru Arkansas a couple of years ago. The 6.7 PSD has always had a exhaust brake. It got better in '15 with the bigger turbo and appears to have gotten even better with the '20 trucks.

I'm sure you'll be impressed with the 6.7 PSD compared to your gas truck.

You have to understand that only two tires are slowing the truck and trailer with exhaust braking rather than eight tires with the service brakes. I have considerably more rear tire wear even with my “weak “ 2011 exhaust brake and have no desire to work them harder, but then I have no standing in the bragging rights club.

This may be OK with a smaller trailer, but even then it's not ideal; I experienced this with 2 diesel trucks prior to my current rig. I was blown away by the strength of the exhaust braking capability of the Cummins when I bought my current truck. I very rarely have to use the service brakes at all on even the steepest mountain grades towing my 16k fiver, and find many times that I need to give the truck some throttle because it's slowing down too much.

According to the RV and Towing guide published by Ford Motor for the 2011 model year, there is an integrated exhaust brake in the tow/haul mode. I mentioned warranty from a third party source for a used truck. Alpha is the brand and one that will cover the turbo and HPFP will cost about $2500 for three years.

Have to say your rear tire wear is NOT related to your EB use. Sounds like more like the GO pedal. :B

Please explain your wording "exhaust braking".

The turbo veins close which creates exhaust back pressure

On a stock 2011?

Yes.... but it wasn’t the best performing exhaust brake

Thanks. That was what I assumed.

So I say pass based on FISH’s explanation.

Just because it’s not the best doesn’t mean it’s not acceptable. I’m certain the 2020 trucks exhaust breaks are better than your truck but that doesn’t mean that your not satisfied with yours

Hook, Line and Sinker!!!

Thanks FISH.

I think all we’re doing is trying to better inform an otherwise uninformed person of the advantages and disadvantages of a particular vehicle.

But Lynnmor, you are getting a bit defensive of your 2011....lol.

It is amazing that folks need a button to play with to make it real for them. I have towed a medium size travel trailer all over the country preferring roads other than interstates and never overused the service brakes. You don’t need to drag the rear tires to have an acceptable amount of control. If one would just know to use tow/haul and apply the brakes to slow just a bit, the truck will handle it from there.

If you buy a programmer or install an inline brake, correct?
Not saying that’s a bad option. Installed one on my 07 Dodge because no exhaust braking from the factory.
But that’s a $600-1500 add to get that performance out of the early 6.7 Powerstrokes.
Add that to a persons budget comparison if planning to use the truck in applications where it would be needed or desired.

And based on the simplistic nature of the OPs question, doesn’t seem like a gearhead that would be interested in modding his truck.
(Or wouldn’t have asked about buying a warranty on an old truck)
