If you want, sure!
I thought it would be cool to NMO mount through the roof for the ham antenna. It worked dope - had great range.
Until I drove into the garage and forgot the antenna was still screwed on.
This did not fuckin work.
Eventually I stopped taking fucking pictures and managed to get a fuckin nut galled onto the fuckin bolt before it was totally flat. So, with the headliner still down, and unable to remove it from inside the truck or put it back up, I drove to AVID in Queen Creek with the fucking headliner resting on my head where Brandon helped me unfuck the bolt out of the hole and we used a differnt bunch of washers, RTV a nut and a bolt to make a little fuckin R2-D2 droid for the roof of the truck.
Then I drilled a new NMO into the roof behind the first one, and promptly drug it across a low hanging branch.
We now use a mag mount on the hood like a fuckin unicorn.
