If you ever pass thru Winchester give me a shout and I'll will help you out:) or maybe we pass near your home base on our trips to western NY,WV and KY to see our families every year.
If your rig has a rear window ( our's did not) you could just wait until one of those Decatur MVR-725's or a similar old K band police radars from Kustom or MPH show up on Ebay and mount the antenna facing aft. The only thing you would need to do is lenghten the antenna cable with a four or six wire cable. It is all low voltage DC and safer that Christmas lights:)
