I have a 2012 Sub 1500 LTZ, with automatic level control.. (air shocks) I tow a large RV. My WD hitch cust serv sez to turn off the ALC before hookup, & during towing. They are right, the ALC lifts my front, & negates the WD effects. Lots of sway & porpoising. If I put an on/off switch in the cab on fuse #2, or 54 or 58, will the compressor valving hold psi in the shocks? Will this idea work?
Which of the 3 fuses should I conex to the switch ? This truck is new to me; my other Sub towed this RV fine with same hitch.
