All season tires are okay in snow if they are new, but winter tires are way better over the life of the tire, and are always better on ice and in the cold when other tires are as hard as hockey pucks.

I will use mine gently as a truck, towing a boat or smaller trailer, and hauling lighter stuff (firewood, a deer or elk...), but it is mostly a car, and will never go off road.

Meh, you're right. Nothing beats a real winter tire I guess. I will have summer wheels so these by default become winter rims and tires.

You're right about that. I plan on using my Harley like an suv. Hauling kids and groceries. Nothing really dirty going in my bed! That's what my son's truck is for! I'll use it to tow a small 5x10 enclosed trailer, but that's about it. Only off roading would be an occasional wet or muddy field. I was going to get an expedition, but this truck just looks cooler.

Once again my truck slid down the driveway. I have noticed that it slips a bit when the engine is turned off. So I did some testing. In 4X4 or AWD mode the front wheels unlock when the key is turned off. This is a safety issue if you ever park on a hill or a boat ramp. Turn the engine off, and the truck slides. As the e-brake only applies to the rear wheels, it is of no help.

Seems like a big safety issue to me.

It is called 4 wheel drive, not 4 wheel park. I would install some sort of wheel chock or something If I thought my truck would roll down the drive.

My previous vehicles would stay put in 4WD mode, but slide down the driveway in 2WD mode, as the two locked vehicles would not hold the weigh of the vehicle and the two non-drive wheels would roll.

I was very surprised to find the truck on the road this morning. It just missed my wife's jeep on its adventure. I drove back up, and put on the parking brake, and it moved only an inch since then.

Possible scenarios: 4 WD does not lock. Or perhaps did not turn on the 4WD soon enough and it had not yet locked. Or maybe it is the tires that came with it. Not so good in the snow. I did drift on the highway yesterday in a bit of slush. (Another unpleasant surprise)

Does anyone know the technical details?

I saw this message and thought deja vu. I've seen this exact same post before on a dodge truck forum as I use to own a dodge. It seems to me you buy alot of trucks but your wife keeps driving the same old jeep. She must not be very happy.

On my 450 it is hit or miss on the hubs unless you leave them in manual lock. But the transfer case never unlocked. thw 150s use a lockup collar on the msf and esf t cases and they stay locked. On this limited (awd tcase) there is no way to lock the front axle. Because they use a clutch pack that is electric and will not engage without the truck running. Engaging the t case in 4x4 only locks the clutch pack there is no splined engagement. The all wheel drive mode senses wheel slip applies power tithe slipping axle and pulses the clutch pack when there is no slip so you don't feel any crow walk or bind.
