1. A “truckers” (CB) radio is exactly what I was suggesting FRS radios as an alternative to.

2. I suggested them because they are much simpler to use. With a mobile base station you need to figure out where to mount it in your car, where to mount an antenna, tune that antenna, how to hard-wire it into your car’s power (or splice an adapter onto it to power it from the cigarette lighter), whereas with a walkie talkie you just need to turn it on, put it on the right channel and push a button.

(Handheld CBs do exist. I’ve very rarely seen them for sale in a brick and mortar store)

3. It’s probably gonna depend on where in the country you are, but CB radio equipment is in fact not commonly available at gas stations and truck stops around me. It’s something I actually actively look for and take notice of because I’m a bit of a radio geek. In fact, if I needed to tell someone where to get a CB locally, their best bet for that would probably also be the-store-whose-name-you-seem-too-think-that-no-one-should-say-like-its-fucking-voldemort-or-something, and even that would be hit or miss, some TSWNYSTTTNOSSLIFVOSes don’t actually seem to carry them, but every TSWNYSTTTNOSSLIFVOS I’ve ever been in absolutely has at least one set of FRS radios for sale.
