Water level indicator light ???

Opening the belly isn't as scary as it looks. Pull down a little bit of the cover til you find what you want and then go for it. I got into mine to reroute the brake wire for discs and to put in a better flowing tank drain and I ended up doing several fixes. I replaced the dinky drain tube with all 1/2" threaded ips plastic fittings and ball valve, got the droops out of the vent tubing etc, etc etc. I also teed into the drain pipe just above the new ball valve and put in a 3/8 barb/tygon tubing and ran it up the outside of the frame so now I have a sight gauge for the tank. I missed having the water tank where I could see it, like in our previous smaller 5ers... not anymore! Craig
