I bought a P3 from Mantelli
Tekonsha says it's their best, even though I've only got e-brakes, for a few dollars extra to potentially tow something with multiple axles or electro-hydraulic in the future is was not outrageous. You never know what the future will hold.
The price was better than stated above and it included a 2nd vehicle kit plus free shipping to the lower 48. Mantelli was great to deal with, highly recommended. (A big thank you to Steve L for the assistance in installing it)
I've never used a brake controller before and was amazed at how well it adapted to different braking situations. Maybe it is over kill, but whats a few dollars when one considers the cost of a trailer and tow vehicle and their contents.
IMO adding brakes
and a controller took a lot of concerns off towing with my 94 Ranger that has weak brakes
to begin with. The RABS valve only seems to hold up to a single hard braking situation before failing and shutting down the ABS system. I've replaced that 3X [at] $175 plus labour before giving up.
