Re: CB Radio
Cool. You probably know this already, but if not... diskcones have really low gain numbers. Like, almost unity. An RF amp will help offset line loss if it's a long run back to your radio (details).
Radio Shack sells a generic diskcone (product link), but like most it runs out of gas below 6M (50 MHz) and is a tad fragile. The upshot: easy to assemble, can pack into a tubular container and cheap. I'd have a look at more professional models (Diamond Discone D-130J comes to mind) since Rat Shack's has a SO-239 connector, which is a dead-giveaway they haven't a clue (or care about) return loss. The D-130 (product link) comes factory fitted with an N connector, which is *much* better suited to shorter wavelengths. The irony: there's $40 difference in price.

If you look around on your firewall, you'll probably find a couple of rubber plugs that are already filling in holes. They're there for options that your truck doesn't have. You can normally just drill a hole just a little smaller than your coax and feed it through. That's what I've done on several occasions in cars and never once had a leak. But if you're concerned about leaks you can always seal around it with silicone.

Re: CB Radio
Did you mount the antenna to the box or to the truck body? Your antenna is going to require a good and proper RF ground to function efficiently and not risk damage to the output of your radio.
Just another thing to consider. If it is mounted to the box you can ground the box, you just need to make sure you are using a braided ground strap instead of a simple wire. Your antenna needs a radio frequency (RF) ground, not a DC ground.While many claim to support the right, precious few support the practice.
