Have YOU personally towed with a 4 speed auto trans Cummins on 5-7% grades with 15-16K combined load? It's almost like going down hill in neutral. Dropping a gear does not help much! Plain and simple you are using truck and trailer brakes to control speed. But hey I guess that's what those emergency ramps are for.;)
She sad, "I would love advise from any of you with experience with these trucks if it would be a good idea for me to add the extra accessory brake? It will cost $2500."
I don't see anywhere her mentioning money is tight? Nor did she mention a Salesman saying it was needed. I did see where she wanted "advise from any of you with experience with these trucks".
I've done with an old ford 7.3 (no exhaust brake) and I stand by my statement...nice to have but far from necessary.
If cost is irrelevant...I assume she would have just bought a new truck. Of course, she did indicate cost was a factor as she said a new truck is out of her budget, so the relative benefit to cost is important.
She also didn't say she was going to spend a lot of time driving in the mountains.
