We don't have an EB brake and for what we tow it is not needed but I can see it would for a much bigger fifthwheel and I know I would like it. Starting slower down steep mountains is the key.

Really, you think that 35' Alpenlite is that lite? Maybe you feel you don't need one if you don't have one, but after installing mine, life is far better coming down a long steep grade.

The hills in the Oregon Coast range have some good grades in them, I can be traveling down at 60, drop to 4th (5 speed manual) and be down to 45 without touching the service brakes! If anywhere along that downgrade I need a panic stop, I still have COLD brakes both TV and 5er!!

I see an EB to be like 4X4 you don't need it UNTIL you need it!!!

Russ Larry's GM has grade braking unlike our Dodges that did not lock the TC in OEM trim! V8's seem to hold back better also. BIG difference!

I have the exhaust brake on a secondary switch to my smart controller and even with the TQ locked, the mighty Cummins just free wheels. Chris

If my Pacbrake worked that poorly, I would demand my money back. I have the advantage of a manual 5 speed, and I also bypassed the ECM, so my Pacbrake is also instant on no delay.
It is also activated by compressed air @ 150psi. I very seldom need to even tap the service brakes on a down hill.
Maybe someday soon I will get a chance to come down the west side of Lookout Pass on I90 in Montana's Bitterroot range!
