Mike, It can be done, and others have done some work in this area as well.
The changing layout of the different coaches makes almost each change unique
to the particular coach being updated. Probably a good idea to do a lot of
comparison and measuring before undertaking the modifications. The ride
height sensors are subject to failure of the led's and phototransistors and
because they are molded in epoxy, are almost impossible to repair. If
someone wanted to bite the bullet like the guy in Lincoln City that makes
the Dinosaur circuit boards for the furnaces and water heaters, to create a
replacement board using more modern electronics, it would sure be nice. Junk
yard stuff is just that, junk of unknown quality until you buy it and test
it. Also personal preferences apply here. Some people just replace all the
hoses, valves, sensors, tanks, compressors with shrader valves in the end of
the air bag and use their coaches like that and enjoy the heck out of them.
Some guys want the most high tech system that they can put in their coaches.
I don't think either approach is all wrong, after this is still America,
land of free choice. Step up to the bar, pay your money, take your choice,
live with the results.
