it's normal, oversteer and understeer, all cars do it, just some are more pronounced than others. If you learn how the car/truck responds each way it helps to straighten out the esses, and you can outrun a lot of people who don't know how to use it.
It has to do with traction, weight transfer, and car design
A short explanation (but of 'extreme' case, it's a racing page after all) is available here:

scroll down to the trailing throttle and power on section.

Haven't read it all yet, so haven't seen where they're going with it.
Most cars are pretty light on it, and 90% (at a guess) of drivers compensate without even realizing they do it, my old B2 was fairly strong on power on oversteer, and I never realized how much I automatically corrected for it untill I was in a race, and missed a shift, and almost went in the ditch, because when I missed the shift I corrected for a force that wasn't there.
If it's abnormal for the truck/car check bushings and spring mounts, alignment and tire pressure.
Like I say, if you get to know how your truck acts under those conditions, you'll be able to get out of some scrapes, and outperform people who don't know how to handle it. say You get in a curve, and need to tighten up or hit the ditch, if your car understeers when braking, you'll know that hitting the brakes wont keep you out of the ditch, and that you should give it a little kick to tighten up the curve.
three things I do when I get a new truck or car, and the reason they're important to me:
learn where the tires are, try to get each tire to a certain 'spot' untill I know what to reference off while in the car, because if I'm out playing and have to miss a big ol rock I can't realy see, or have three inches of clearance for a drop-off, so I know how close I am to it, keeps jack use to a minimum.
Figure out the power on/off under/oversteer how much at how hard on the throttle, because when some moronic fruitcake in a wimpwagon in front of me gets a phone call, or mascara in his/her eye, I want to know what my truck is going to do when I have to avoid him.
figure out exactly how big of a space is NEEDED to drive through, and what it looks like from the drivers seat. just because those DNR trucks are BIGGER than my truck! That's purely hypothetical of course, I'd never be anywhere I'm not supposed to be so I wouldn't have any reason at all to try ditching the dnr.
