Does this sound about right?

If you're not in a hurry, browse craigslist for used radios. I've bought a few Cobra 29s for $30 or less and they were near mint condition.

 

Was that shop called CB Radio Shop ? Was it down the street from the TA on Guasti Rd?

 

Just shootin' from the hip but the install price sounds darn high to me

 

Sounds about right price wise.
If I was in the business I wouldn't touch a truck for less than 65 bucks an hour. Some of these installs can be kind of nightmarish and end up taking all day trying to chase down ground problems.

 

No it doesn't unless there is a guarantee it will work right and if it does not, they won't charge you to fix it.

The coax install should be at $150 at most. A good tech will do it in less than an hour and a half, lousy ones will take three hours.

 

And how many hours did it take you on your friends Freightliner Cascadia?

 

Running the coax was about 35 minutes. It took maybe another 20 minute to pull the panels off.

 

Kinda depends upon how clean of an install you want. Wires and coax out floppin in the breeze for the world to see? Or tucked away and ran inside your mirror mounts? The radio will be checked out and maybe pumped a bit. Nothing special. They will / should be matching your SWRs for the set up. That stuff takes time and won't be a wham bam job. Betcha it should take a couple hours to complete IF done properly.
