What chassis do you have. I had a problem one time with my speedometer and I took it to Freightliner and they fixed it. Not sure what they done, but my point is take it to the chassis builder and they can fix anything. Mine was still under warranty when this happened. As many gauges that have failed on yours it could be something simple that will fix it.

Example: I have a new Honda CRV that I bought in 2013. Anyways I was at a RV park by Lake Otay near San Diego. I noticed that there was a lot of wild life around the campground like rabbits, squirrels and coyotes. I went to start my CRV and it cranked and cranked finally it started but on the cluster of lights three of them were lite up. One was the electric power assist light, the other was a traction light and the engine light. I could not accelerate the engine, it would only idle. So I towed it to the Honda dealer where I had bought the suv. They found right behind the block three wires cut. I guess a squirrel decided it wanted to eat some electrical wires. My point is that it could be something simply as that on your problem with the gauges on your coach. Did not cost me anything because it was still under warranty and they could not prove that it actually was cut by the sharp teeth of a squirrel.
