I can definately agree with the XJ at least needing more brake when towing anything over 2k lbs. I have on a couple of occasions had to pull a friends car with my rig and upon going down a moderately steep offramp of the freeway, found my foot pressing the pedal almost to the floor to stop remotely quickly.... I'd like to find out now how it would work with my new ceramic brake pads
. What I'd really like to do eventually is find an excuse to use my electric trailer brake module that's collecting dust in my travel toolbox (probably need to buy a trailer first).
