Morning all,
The wife and I where discussing vacation plans. We were talking about places to go on vacation. Colorado came up. We haven't been out west in quite a while. Never been there with a TT or 5th wheel. We currently have the truck and 5er in Sig. The truck is stock. Is an EB really necessary to go to the mountains?
I have been researching a mod to use the exhaust back pressure valve as an exhaust brake. Has anyone here done this?
We haven't decided where we will go on vacation this year, but if we go to mountains I want to be ready.
Thanks, John

I drove an F450 for 10 years sans exhaust brake. I wished I'd had one in the mountains, but, in over 100 thousand miles my brakes never needed service.

Now that I do have one (engine brake) I love it and wouldn't be without it.

My prior TV was a 7.3 PSD Excursion. I did the EPV exhaust brake mod and it made a night and day difference. I was towing a 10k loaded TT.
Towing in the WV mountains the exhaust brake made a huge difference. It's nice to descend under control vs. riding a roller coaster!

IMHO Since we all tend to put a little more weight on our vehicles than we should, I think so.
Even though it looks like your rig is sufficient, I honestly believe every little bit helps. I don't think you have to not go anywhere without it right now, but I would get one. I got one on my 90 250 and immediately noticed the assistance in braking. Have had one on every engine since. Wouldn't plan on not having one anymore.

You are in luck as the warm up butterfly in the turbo can be tricked into a surprisingly good exhaust brake for not much money. If you have the manual tranny a simple toggle switch putting 12V to the plug on the turbo will work. With a auto it's more complicated as you need to lock up the torque converter even if you spend big bucks to put one in the exhaust pipe.
Years ago you could buy an electronic exhaust brake for the 7.3 on Ebay for less than $100.. There was a chip maker that had one but I cannot find it now. Do a google search to find how to do this as it really works and with a diesel in the mountains you really do need an exhaust brake.

Is it needed? No. Is it nice to have? Sure.

We went up and down several mountains in Montana with our rig. Never out of control. Pay attention to what your doing, keep from being in a rush, and you will not have any problems.

The OP does not have the "Tow Haul" option. You might want to reconsider your answer.

An exhaust brake will certainly be a nice thing to have on my next truck. I have no exhaust brake on a F350 with 6.4 diesel, 5-speed automatic (I notice that yours is 7.3 diesel); weight of truck with fiver is 20,500 lbs.

My combination holds 9% grades without dragging the brake, BUT I have to be in low gear. Brakes on truck and trailer have not needed replacement after six seasons of towing. So it is possible to do a Rocky Mountain trip without exhaust brake. Just slow down and get into gear BEFORE starting down any long grade.

As long as he finds an after market device to lockup the TC he will be fine. Chris
