For those using a prodigy controller I under stand you can disconnect it when towing in reverse for 3 or 5 minutes. This is probably to prevent problems.
One question I had is in reverse is this where the internal magnet wiring might get messed up and cause problems? Shouldn't but I doubt the mfgr's worry to much about such stuff the longer I read about this industry.
I am going to use 8 and B2 for my settings.
For Duramx owners using this controller with the Allison tranny.
How has your success been cresting a climb and letting the tow haul mode control your descent.
I will probably crest and get the unit to about 45-50 depending on the expected grade and let the tranny make the calls on the descent hopefully only needing the brakes very occasionally. I also will probably put the controller in B3 so the trailer leads the truck alot more in the descent saving the truck brakes for a big emergency.
Also how do you modify your settings in rain?
We will be in the ROckies but not crossing some of the more difficult roads but we will be on I-70 from Denver to Moab and that has some good climbs and 160 from Durango east and then north to Denver. I have driven both several years ago and I don't remember much climbing at all on 160 east from Durango but there are some nice climbs on I-70.
Leaving tomorrow afternoon.

I pull with the prodigy and a Dmax/Ally CC long bed.
As far as your question about reverse? I don't really understand why you would want to, but you don't have to disconnect it at all. I never have. But if you have to, it certainly won't hurt the controller.
As far as grade braking in the mountains, I can only relay my experiences crossing the eastern ones, (I did the Rockies in a car, doesn't count). The grade braking feature works as advertised. If the hill is steep, then I put the tranny into T/H mode and let it take care of the rest. Remember, you are just have to push the "I believe" button when I tell you that the real red-line on a Dmax is 4800 RPM's when in grade braking mode. The computer won't let you granade the engine and unless you've modified the governor setpoint, it you keep you foot mashed down going up a hill, the engine will not go higher than 3200 RPM's. From 3200-4800 RPM's is where the Engine braking is allowed to operate only. This will not hurt your engine.
When I went from Ohio to Hilton Head SC last year, we towed from Ohio to Virgina in the Rain. I never changed the settings on the Prodigy at all. If you set it correctly the first time and you are used to how the rig performs, then you will not even worry about whether the trailer is braking appropriately or not. When I towed our TT with our Grand Cherokee, I found the boost settings kind of annoying rather than helping. I like smooth seamless braking and the boost setting where just too unpredictable for me.
