Driving along the speedometer & overdrive stopped working at the same time. Is there a fuse that controls both. Our other RV had one. The book doesn't say.

Jim, if you lift the dash panel in front of steering wheel and check the INST-IGN FUSE 10 AMP, plus some body builder fuses in same fuse panel. This is the internal fuse block. You also have a fuse block on fire wall out side. All this info is in WH service manual.
The reason the fuses if they are blowing is your ignition switch cable rides over the top of a metal bend at top of steering post, everytime you move wheel up or down the wires may chafe on this bend and cut into wire causeing fuse to blow. I had a 30 amp blow, out on firewall location. I placed a wire sleeve around these wires to prevent this.
Also this same wire harness has a plug in it that may come loose that you should check if your still having a problem.
