Breedlove Puck Mount or NMO.
The bible of Mobile Installation:

There’s
no good reason to not do a proper antenna mount. Objection is
unreasonable as it isn’t supported by evidence. They don’t leak, re-sale isn’t affected, and they work for decades.
The mount type and it’s location are
the most important aspect of any radio installation, but with
enormous penalties in Mobile when wrong.
Your vehicle is one-half the antenna. The close-coupling of permanent makes the most of that.
To do it right means
it’s completely out of the way.
Mag-mounts get tossed in backseat. Doesn't get used. Then gets wrecked after something dumped on it. Etc.
A low-key example with NMO would be the Laird or Larsen 49” base-load whips.
Sky’s the limit from there. Big & Crazy if you want.
Read at the link. It’s more than one night to get a grip on it. Take your time and get a real plan.
My experience is that most folks who think they know what is CB Radio haven’t been exposed to what is truly possible.
As another radio type might someday be desired, consider getting it right from the start.
A van would be a great mobile. With the right mount.
I get passed by escort vehicles for oversized loads daily. Many are vans.
Very few have permanent mounts. But the ones that do
can out-talk nearly every vehicle on the highway.
Again, read at the link.
Take your time.
