2008 F350 dually, V10 Auto with Tow Command.
When I am towing either of my horse trailers, After coming to a complete stop (stop light, flat and level), the truck "surges" 4-6 times, actually rocking forward. I thought it may be the trailer brakes "pulsing" but we are already stopped and on flat and level, so the trailer has no momentum to move.
I thought the horses where dancing around back there, but that's not the case.(video feed/monitor) I watched the tach, RPMs are steady.
Any Ideas what it could be ??
