That is the blindingly obvious answer, especially with a vehicle as large
as a motorhome.

Sorry, I should have said, the antenna is not mounted on the vehicle. I use
a small tripod. Running one coax shortish coax with a power lead taped to
it is fine but a long , or several long, counter poises are what concern
me.

Then run a "shortish" earth braid from the vehicle's chassis to the antenna.

It really is not rocket science.

You are confusing earth ground with a counter poise..

To establish a counter-poise, the counter-poise needs to be directly beneath the antenna.

Just hooking some braid to the antenna won't do anything.

RF needs lots of MASS - a piece of copper braid does not do this.

Furthermore - a piece of wire 9 feet long would detune the antenna system - since 9 feet is a perfect dipole for 6 meters...

I do not think that the OP is sincere in wanting to do anything since his expectations are unrealistic.

The proper thing to do would be to either fabricate a mount that places the antenna directly on the vehicle, or fabricate a mount that goes beneath the tire that tilts and holds the antenna above the vehicle..

I'm not going to comment about women or the fact that most men's problems revolves around their women not allowing them to do things like this. Sometimes a man needs to grow a set of balls and do what is mechanically / electrically correct as opposed to being politically correct...

Long wire. Gawd he's been banging on about it for weeks now, shirley
you noticed - tales of daring do with a homemade auto ATU interspaced
with yarns about a sporting injury? Did someone mention Walter Mitty?

Of course. For some reason I had taken that to be a reference to a Lyin'
Tamer

Put the tripod on top of the RV and connect the "ground" to the RV top. It
may be not much of a ground on the lower bands, but it should get a signal
out on the higher bands.

For holiday operating I have a set of quarter wave conterpoises taped
together which I load a vertical against (fibre glass fishing pole with
wire attached). It would be trivial to layout the counterpoise under a
campervan.
