ground plane

I'm running an Anytone AT-666 with a Bulletproof Diesel NMO mount and a Laird CB27S 1/4 wave antenna on my 2020 F350. Aluminum body and a panorama roof. SWR is 1.0 on 19 with little increase on either side as 1 and 40 are both 1.2. I understand that CB usage on the roads is not what it once...
