Has anyone looked at putting a pair of infrared distance sensors in the rear of the coach to either provide an electrical input in lieu of the height control valve or with a cockpit display to optimize the pressure control method (ie set your static pressure to get close to desired ride height, but then adjust the pressure as the sensor reading changes). Sharp makes an infrared distance sensor that reads from 4" to 30" although the output is most linear in the mid band from 12" to 20". These things cost about $20 a pop. I'm thinking about setting up a couple on my birchaven with a cockpit readout, but with the existing height control valves still doing the work for the time being to assess reliability and accuracy before considering a conversion to an optical height control system. There are more expensive laser based sensors that are 1200 psi wash down rated, but I can buy 15 of these for the price of one of those.

Suddenly something made a running noise and I said "What's that?" He sad it was the leveling system readjusting because of my added weight (200 pounds) to the coach. He said he was going to fix that some day by turning off power to the system when the coach was parked.

I like the built in delay that keeps it from readjusting on short term highway differences like crosswinds, bridges, tunnels, and curves.
