i work for peterbilt here in houston, idk which trk manufaturer you work with but i know that our cab suspension bags are pretty tiny (in comparison to a suspension bag used on a light duty application) my concern would be if they were rated for enough load (i know that the cabs arent light by any means but a suspension bag goes through alot more abuse than a cab bag being that the cab bag only absorbs whats left after the suspension bag has done its job). now the air rocker switches should work just fine. i do have a buddy thats using a United Pacific compressor out of the add on train horn kits on his truck and it works just fine just takes a long time. i would prob recomend just footing the extra cash for a good compressor.
