Brake controller tips?
Hi - we drive an Infiniti QX80 (tow rating of 8500 pounds) and trail the Sunset Trail 290QB. We have the Prodigy P2 controller. This is the first time we've towed a trailer - previously we'd rented an RV for spring break trips w/the kids.
We've driven 3-4k miles so far with this setup, and the experience has been pretty straightforward. I was pleasantly surprised that towing the trailer was easier than driving an RV. The Infiniti drives very smoothly, and has handled just about everything we've thrown at it.
That said, on our last trip we were leaving Death Valley on the west route (CA 190), and hit a 9% grade downhill. I did not ride the brakes, just periodically used them to slow us down - still, it got pretty harrowing in parts.
I suspect that I could've relied on the P2 more - but it didn't occur to me until after we made it through the pass and got to easier driving. Am I right? Would I have made my life easier if I'd dialed up the P2 to a higher number, forcing the trailer's brakes to do more of the work as we went downhill?
Any tips/tricks for using the brake controller better in steep downgrades are much appreciated!
