    I'll ground the antenna to the frame, but have some
    transceiver ground questions: I found an unused 25 amp fuse where I can pick-up power.
    1. It appears that the negative side of the battery goes to the frame so I can connect there.
    2. What is the best way to ground the transceiver or does the battery negative provide it?
    3. Does anyone bother to actually run a wire the earth/ground/dirt, or use a rubber/copper strap?

    I don't think I'd depend on the (-) cable as a ground. It is one, but a separate ground just seems logical. Short and direct is nice.

    I take it the ladder is isolated from truck/RV frame ground...(?)

    Ahoy!
    Yes. Our RV has wood framing and fiberglass exterior. The ladder is bolted through the wood internal framing.

    I always run a separate ground wire from the antenna if it's mounted on the ladder back to the frame. Sometimes an ohmmeter shows it grounded sometimes not, and that doesn't mean there's a good RF ground.
    Also remember if your running off grid on the battery, when the RV voltage drops below 12 volts it can really affect many brands of radios, particularly Kenwood's and Icom. Be very careful on this one.
