dually 2 wheel drive in snow with TC on

Although I have SRW 4x4, I notice big difference in traction with the TC loaded. In places where I had to put the truck into 4wd just to get moving, I can ease the throttle in 2WD and get moving due to the weight over the drive wheels. I do have a limited slip differential which helps but the weight on the rear helps considerably more. If you are set on 2WD, consider buying a locking differential for it. You would be surprised what 2WD will do with both rear wheels pulling you along but also expect you may get understeer up front because the rear will have better traction than the front.

I have the 4:10 limited slip rear end in mine. I go boondock camping with a bunch of people who have motorhomes and we all tow Jeeps.

I can say that when it snows, I'm the one that gets to test the road because I have 4x4 (or 4x6 if you wanna call it that). I get sent up the road and if I can make in it 2-wheel drive, we send the motorhomes up. If I need 4x4, we find somewhere else to set up camp.

There have been several times where I can get up the road in 2-wheel drive, and motorhomes still get stuck because they don't have a Limited Slip rear end. If you do get a 2WD, make sure it has the limited slip rear end, or add it later if you're worried about it.

If you really want to be a rockstar, add an ARB locker to the rear. That's what most of our Jeeps have. You add a locker and air down your tires, you'll go places that a normal 2WD can't, bordering on what 4x4's do.

Same as racerguy using 2WD. I did it in two feet of untracked snow with my DRW. I do put it in 4WD most of the time to keep my wife happy.

Just for funsies I decided not to put the truck in 4WD and I couldn't hardly get the back tires to spin, no matter how much I throttled it.

Mine does have limited slip in the back, didn't catch whether yours does.

u r saying u had great traction?

The difference between 2wd and 4wd is amazing when things get slick. our lane is all up hill from the gravel road we live on and the gravel road is very hilly.
Without 4wd I always made it in and out but with very aggressive driving and good tires.Many times I would have to back all the way down the hill and back up the other side until I quite moving.Yes weight on the truck helps a lot.But weight does not help when you hit ice in fact it makes it worse.
4wd has allowed my wife to drive in and out of our road anytime she wants. In fact when others have gotten stuck at the bottom of 2 hills on our road she has driven them to the top in one of our 4wd truck or jeep and I have driven their vehicle out.
We avoid driving on snow or ice because of other drivers we may encounter. Especially on the interstates. Every time it snows somebody looses it and crosses over the center into the other lanes and when someone is spinning around coming down the road in your lanes there is not much you can do.

Up here in Mi where it snows from thanksgiving to may day, you just rarely see a 2 wd anymore, let alone a dually. Years ago when a work place had one we ran with 3 engine blocks in the bed, only on sunny days, both of them. Kidding aside with that much weight and some carefull driving you should be fine. Its not a good combo by any means. Any body that thinks a 2 wd will go anywhere a 4 wd will go is flat out full of BS and has never tried to make it up my driveway in December won't happen. Normal highway tires are fine the narrower the better more pnds per sq inch on the road surface. Id probably try to head south more than north after deer season.

My flatbed also doubles as my plow truck in the winter. With ballast sand, plow and snow blower, I have around 3k of weight added. When plowing, I'm always one of the first on the road and 1-2 feet of snow does not slow the truck down much. Weight does add some benefits as it keeps the tires on the pavement instead of riding on top of the snow. Ice is a different story and demands a lot of caution.

A friend of mine living in Wyoming told me he uses for his 1985 Ford F250 two old Truck Tire inner tubes makes cuts in tubes filled with fifty pounds of sand. He ties them off in the bed and hangs the inner tubes above the wheel fenders on both sides, of his truck. He said he has never any problem with snow in a empty truck. When weather is too bad you don't go out.

My 2wd dually, with all season Michelin 235/85-16 tires with the 4000lb camper on works amazingly well, very competent in snow packed snow or ice on winter Canadian mountain passes (I always carry chains just in case). With camper off it's horrible, bordering on dangerous.
