I need some advice on a brake controller. I've never towed anything large enough to require a controller, and therefore have no experience with them. However, I will be renting a 19' travel trailer this summer, and the rental place requires a controller to be used. Although they rent the controller for $35, I'm thinking that I'd just rather buy my own, in case I have a need for one on down the road.
With what little research I've done, it seems the Tekonsha Prodigy and P3 consistently seem to get high marks. For those of you with more knowledge / experience with controllers than I, what would you recommend? What advantages does the P3 offer over the Prodigy? How easy is it going to be to set up, given the fact that the first time I use it will be when I pick up the trailer? Anything else I should be aware of?
