I would recommend the
SMI Air Force One
I was very satisfied with my install and the unit mimics the M & G in performance and set up, with the caveat that SMI is an iRV2 sponsor as well as a participant in these forums....
I've used SMI products for several years, the "Stay and Play" before the Air Force One..... I towed an H3 Hummer and then a K3500 Crew Cab behind my '07 LADB and the unit worked without incident....
Why not support those vendors that support our forum, as it keeps the forum running..... and free!
