Which antenna do I need ???

[JesseJamesDallas]

The truck is aluminum....Most antennas are "ALUMINUM"...why would you think a aluminum antenna wouldn't work on a aluminum truck?

We're not talking about a plastic truck...And even then, like allot of Big Rigs now days that are mostly plastic or fiberglass, they still run regular aluminum antennas....

NGP antennas are for things like boats and RV's.
