I've got the hitch on the X5 already, but I also plan to tow my camper with my Toyota Tacoma. While this is more expensive than just having a regular Prodigy controller (which I've already got too), it will certainly be cheaper than having a brake controller wired into the X5. That, and I don't have to worry about a mounting spot inside the X5 (or the Tacoma for that matter....)

I'll then be able to just move the remote from vehicle to vehicle, depending on which one will be used to tow the camper.
