I am putting a full 1/4 wave 6m thin whip NMO dead center in the roof (with a metal shock spring). Maxrad whip, and Antenna Specialists base and spring. Looks sharp and works much better than any base loaded model. If you are looking for a good 10m antenna that is somewhat shorter and NMO mounted, the Motorola Spectrum antenna for 30-39 MHz works very well on 10m...almost as well as the full 1/4 wave I ran back in the day. Many troopers use these now, although I love the look of the old ball and spring.
I have a High Sierra screwdriver for HF that mounts in the tow hitch. It works well there. 10m is covered, as is HF down to 80m.
I love the old ball and spring mounts. I'm getting a new work truck soon and want to put one 10m on one side, and a 6m on the other...if my boss is ok with that. He is a ham as well. Then I want to run a Mitrek on 10 and a Mitrek on 6. I have a LB Syntor X9000, but I think the Mitreks are much better radios.
