How can you tell if your truck is pinging or not? Does it just run like crap, or what?

A kind of clicking sound under load is the easiest sign to detect.

You will notice it most when the engine is under load (like climbing a hill or accelerating). So, stomp on the gas and listen for a rattle/knocking sound which does away when you let off.

Common engine "ping" or spark knock is noticed mostly when under light load conditions while at lower engine RPMs and is generally harmless. Persistent ping can be an indication of a problem, especially if you notice it a higher RPMs (over 2500) or during aggressive acceleration.
Engine ping is what most people actually hear when they mistakenly tell you they hear the valves rattling.

Besides you having a ping problem you might want
to do something about it.
Most times, it's simply telling you it's time for
a tune up. This includes the normal stuff you
replace in a tune up like all filters, plugs,
cap, rotor, wires but also have the timing
checked.
Now I'm 100% sure I'm about to get flamed on the
above suggestion by someone that NEVER changes
anything on his ride untill it reaches 100k or
more but that's his problem. It's up to you.

Pinging sounds like rocks being thrown around inside your engine. It will never happen at idle, may happen at part throttle, but is most likely to happen at full throttle. It is usually accompanied by a small amount of smoke out of the tailpipe, but don't rely on that.
Pinging is like... taking a cutting torch to your combustion chamber. Your engine can stand anywhere from less than one second to perhaps minute of pinging before it suffers permanent and serious damage, depending on conditions.
The hotter your engine is, the more likely your engine is to ping. The farther your timing is advanced, the more likely your engine is to ping. The higher your compression ratio is, the more likely your engine is to ping. The lower the octane of gas you use, the more likely your engine is to ping.
So, in order to minimize the risk of pinging, do the following:
Make sure your engine doesn't over heat!
Make sure your timing is not too far advanced.
Make sure your compression ratio is not too high (< 7.5 to 1)
If necessary, use higher octane gas.
