If you look at auto tuners designed for use on a whip or long wire the components are rated at much higher voltages than LDG uses because a random length wire or whip can have some wild impedance and very high voltage at the feedpoint.

Using your tuner at the radio end with the stock balun at the antenna and no radials makes a pretty grim antenna. It might make some contacts on the higher bands like 20 or 17m but not on 40 or 80. Put a bunch of radials or a couple of lengths of chicken wire under it and it will work much better. Put an SGC or similar wire/whip tuner on it with some radials and you won't recognize the antenna any more, it will impress you.

Does your RV have a metal skin? If so its commont to mount verticals to them and use the vehicle as the ground plane or counterpoise. You would still need an autotuner at the base of the antenna to make it sing.

I have an Airstream trailer so I have a 30’x8’ aluminum roof with which to play. How to mount this up there is a different matter. Perhaps a mobile antenna of some sort. May need a different antenna? Better option than what I have?
