I did. And have s good SWR setting now. 1.6 on ch 1 & 40 and a 0 on ch 20. I ran a grounding wire from my antenna mounting bracket down to the inside passengers frame rail just aft of the fuel tank. Great spot there for a good ground. I used 50' of high quality coax that l ran along the passengers frame rail on the outward side of the frame all the way up front. I opened the Engine hatch and brought the coax inside from there.
Using sticky velcro I attached the CB mounting bracket to the dash, same with the mic holder. Very clean install and for a RV pretty good SWR match. My antenna is a 4' fiberglass tune able tip fire fly, the radio is a realistic TRC-465 SSB 40ch that's peaked, tuned and unlocked. So far I've talked about 20 miles.
