I just looked it all up online real quick, but don't count out truck stops.
Some are pricey, but some are pretty good. I have a 3ft Wilson Flex antenna I just picked up to replace my rigid antenna that I paid $27 for at the truck stop. The HD mirror mount I listed says $12, but I think I paid more like $5. And coax listed is a brand name, but I got some no name stuff for less than $10 for 18ft. As for the radio, online is likely your best bet.
Drill the hole for the mirror mount to the size for the tire carrier bolt, and throw away the other half of it. I used some heavy gauge wire that I had to ground my antenna. I just used some waterproof spade connectors with a bunch of dielectric grease smeared on them at the antenna, and then ran the wire through the tailgate along with the coax. The ground wire is grounded to the body with one of the subwoofer bolts. Then ran the coax to the front under the carpet and/or under the plastic trim pieces so there is nothing showing.
