just saying if you are going to use 4500 chevy cutaway motorhome and pull a trailer with brakes....BEWARE
the brake switch that would normally be accessed to ativate the trailer brakes is now a position sensor(reostat). trailer brake now goes through the body control module or the cigar lighter or something.
nothing that $5oo.00 can't. plus a full day and 1/4 take of fuel.
