That would be my only reason. I think there is a little less tolerance for imperfect alignment with the single drive arm. The AMPs on my old 2500 were flawless for over 10 years and 120,000 miles. I did have to replace the computer module just prior to selling it, but that was because of a bad crossover cable that fried one battery and surged the whole system. Rough Country intrigues me because of the price difference, obviously. RC and GoRhino are both intriguing because they do NOT require an OBD splitter to keep an open port.Completely flush in the rear , something I’ve not seen in the few Amp
Installations I’ve been around . Two motors versus one , you prefer two , any big reason , other than the walking effect you claim , which I haven’t experienced, nor seen as said on others ? I can’t think of one reason just having one instead of two , and the flawless experience I’ve had with Amps .
