As you might suspect, the more expensive units are all pretty good.
SSB is becoming much more popular, but if you intend to hang out mostly
on ch 19, an AM rig is fine.

I tried the bed rail mount idea. It doesn't work that well. It's like
mounting the antenna on a pipe, there isn't a good flat groundplane
directly under it and a 1/4 wave really *wants* that groundplane.
There's also the issue of clearance height. I took out a row of
fluorescent lights the first time I drove it. Ideally, you'd mount
on the cab, but that makes the clearance height problem untenable.
The second best mounting is in the center of the bed, on the fifth
wheel hitch if available. Naturally this cuts into the cargo hauling
capacity of the truck. So that leaves us with the traditional bumper
mount. That really works OK, and is the method I'd recomend. You
can get an adaptor that fits the trailer hitch that works super,
or you can mount directly to the bumper off to the left side. I
like the center mount because it gives a better radiation pattern,
but practical concerns often dictate the left side of the bumper
mount. Use a piece of vacuum hose slipped over the antenna to avoid
it's shorting to the body if it whips around. One 1/4 wave steel
whip is pretty much like any other, just make sure the mount ball
will fit on the surface you intend to use for mounting. You don't
need or want a spring. The whip has plenty of give by itself. Use
good coax, not that cheap RG58.
