You're not going to downshift and cruise on down the hill with your feet flat on the floor towing a trailer. Most vehicles won't even do that empty.
I do exactly that - I usually let the EB do all the work and don't even have to touch the brakes except to slow for curves.
All your statement does is show that you've never driven anything with an effective EB. Nothing more.
Regarding Op's question, that engine will be far less effective than the 8.1L in your sig. And the 8.1 in your sig will be far less effective than a modern Cummins, Duramax, or Scorpion.
