Good price on a good truck
Yes, 2 wheel drive truck is probably the worst in snow and mud, front wheel drive car would out perform it.
But you would have 4 wheel ABS so stopping should be no problem.
Yes, you will need to put some bags of salt or sand in the back during winter months, put it as far back in the bed as practical, behind wheel wells.
And if possible secure the bags in a net or put a board/barrier across the bed, in the event of a sudden stop, accident, you don't want heavy bags flying towards the cab and the back of your head.
Snow tires have a more aggressive tread design for traction and a softer rubber compound so it doesn't get too hard in cold weather, but because of this they wear out very fast if used in warmer weather.
Studded tires are banned in Southern Ontario(St. Catharines), which IMO is dumb since accident prevention far out weights road damage dollars according to any studies ever done on this.
But an accident costs insurance company and driver money, not the Government, lol, so ban on studded tires saves people who can ban something money, so to heck with the voters and their children getting injured or dieing, "and we winter in the Caribbean in any case so F'em."
I would look at getting 4 snow tires before next winter, many tire sellers also offer discounts on changing the summer to winter and winter to summer tires, i.e. a set price "for life" of tires to dismount and remount and balance, and also free/cheap storage of the unused tires, if you don't have room at home.
3.0l is a good reliable engine, it does have a problem with Cam Sensor Synchronizer wearing out around the 80k MILE time, you will hear a high pitched squealing almost like a slipping fan belt noise coming from the synchronizer(rear top of engine).
Not expensive or hard to change, but do change it as soon as you hear that noise, as this device also runs the oil pump.
On the back side of drivers door will be a Label, it will have the vehicles manufacture date, weight and stock tires size, at the bottom it will have the AXLE code, look here:
This will tell you what axle/differential you have.
The Differential transfers power from the Driveline to the axles, because a vehicle must go around corners the rear wheels/axles need to be able to rotate at different speeds, so the differential can not drive both axles directly, there are two kinds of differentials:
OPEN is a standard differential used on most vehicles, the easiest wheel to turn is the one that gets the power, yes the easiest, lol, this means if one wheel is slipping, it gets ALL the power, so................easy to get stuck.
L/S means Limited Slip, Chevy calls this Positraction, Ford calls it Traction-Lok, what it has is a clutch system in the differential that trys to equalize the power, so if one wheel starts to slip/spin some of the power is transferred to the other axle.
And there is a 3rd type but not stock, it is a Locking differential, it is controlled by the driver, you can manually lock both axles to the differential, so both axles get power full time, but this is only for straight line driving or slippery conditions when wheels can slip when cornering, or an axle will break.
Just an FYI that may help you if you have an OPEN differential, if one wheel is spinning, slowly apply the emergency brake this will brake the spinning wheel more and make the other wheel the "easier wheel" to turn, so transfers power to the other wheel, but you do need to release the E-brake as well so wheels can turn, tricky maneuver with foot brake and hand release, especially with manual trans, but it has got me unstuck quite a few times, but not every time, lol.
And this is when the bags of salt or sand come in handy, you can use some of that material under the tires to gain some needed traction.
Axle code also tells you the gear Ratio.
3.73 is standard, it is good for towing and gets good gas mileage
4.10 is better for towing and acceleration but less MPG at highway speeds
3.45/3.55 gets better MPG at highway speeds but harder to get going especially pulling a load.
