If you are hooked up to the motorhome lights properly, you should have 12 VDC in the dinghy. Your coach probably has a bank of 2 or 4 6 volt batteries for the coach and possibly for the chassis. It might be possible to have hooked the lights up incorrectly, but highly unlikely.

Also check the connections and ground for both coach and the dinghy as well as the cable.

If you are measuring 6vdc under load I'd suspect a poor connection. Try measuring without a load to confirm voltage.
If you are measuring 6vdc w/o load I'd suspect incorrect wiring, as TXiceman said highly unlikely. To check that try measuring the voltage at your M/H tailight assy brake & turn signals.
If you are measuring 6vdc at the Jeeps tailight assys. and the Jeep light blinks OPPOSITE the coach, you have a bad ground and the brake/turn signals are grounding through the tail lamp bulb. The filament acts as a resistor and drops voltage.

Looks like it might be solved, the tail light connector (hoppy: made by hopkins ecectronics)
is not testing at 12 volts.
Thanks for the responses

One common problem is a bad ground on the light line.. For one thing I do not think they use big enough wire.. But this makes for some strange voltage readings.

biz....sounds like you got your problem resolved. Something that is often forgotton is that people test these units without actually having the two vehicles connected and their is insufficient gorund size when they're not.
