I have the odyssey II which I think is what you meant. I also have 2 P3's and 1 something else I cannot remember.
The odyssey II was the last one I purchased, and wholeheartedly reccomend it.
I am driving the truck with it in it today. It is on preset 1 right now which is set for the empty trailer, and as they are dumping the gravel in I will switch to preset 3 which is set for 3.5 tons on the trailer. If I was loading mulch it would go to preset 2 which is about half way.
Brake Controller
bought mine here, there is a (or was) a % discount for TBN members and they are a supporter here.
You may not have the situation that I do of multiple drivers, trailers and weights, but the convienince of having the presets is very nice for me.
We have had several discussion's on these in the past that should come up on a search in this forum.
Good luck, if you are looking at this level of controller, I think they are all pretty dang good.
