PW Excel battery tray

I have an 09 PW Excel. I find that the carrying handle for the coach battery sometimes prevents the tray from sliding out all the way. I reach in after unlatching the tray and push down on the battery handle and the tray slides out enough to check the water level on mine. Of course yours may be different. I also have the Firestone Air bags. The left/right switches are in the cabinet above the front of the RV. There is a left and right switch. I don't have what you call a remote control. Push each switch up and the pressure increases in each air bag, pull it down and the pressure decreases. I don't know if this information will answer your question. I don't have an actual "remote control".
