1k of playground sand in the bed should fix your problem. Or you could look at a more aggressive tire, which not everyone wants. We have packed snow and sheet ice on most of our secondary roads right now. Most of which should be gone this week, as temps are supposed to warm up at end of week.

I'm running around right now with 4wd engaged since I have no weight in the bed, and just driving around secondary roads in town. If I put the ballast weight in the bed, I can run around in 2wd without issues. Doc says I can't lift any weight for a while yet, still recovering from hernia surgery.

But even with my BFG A/T ko's, you can't start off up a hill with a sheet of ice or hard packed snow on it in 2wd without some serious ballast weight. Get you some bags of sand and try that. I would go 1k or 1500 pounds if you're going to do it, 2-300 pounds is a waste of time, the truck will never know it's there.

 

I looked up the ballast amount on the Fisher website and they say at least 480lbs. I'm going to grab 600lbs. of tube sand this weekend and give that a try. If she still spins and I have to keep putting her into 4wheel I will be buying a set of tires and selling these ones that are gently used with a whopping 6800 miles on them.

 

I changed my Michelin LTX A/T's out tonight at 9900 miles for 275/65/20 Goodyear Duratraks. I will hit the backyard tomorrow and see if I get stuck in the same place I got stuck Sunday and report back. It is a shame the Michelin's wear well, and are pretty flawless on the highway and towing, and not terrible in the rain. Snow, mud, wet grass, wasn't fun at all, well we shall see how the Duratraks do.

 

My F350 with the stock Contiskiis was pathetic in snow, especially if there was any kind of hill. My gravel driveway isnt very steep at all, but does go up maybe 5 or 10 feet. If there was an inch of snow or more, no way in heck the 350 could make it up the driveway in 2wd. Believe me I tried every time. Taking it easy feathering the clutch or gas, getting a running head start, trying to use slight braking to get the LSD to do anything... almost always had to pull on the 4wd handle.

Now last year I switched to duratracs and it did make a world of difference. Still get some spinning in 2wd but not nearly as bad (wish the LSD would do something, anything). Weight of course helps too. I don't have a plow, but figure it will take a few hundred pounds just to balance out the engine anyhow. I just stock up on salt bags for the water softener, usually throw 10 in the back.

One thing I don't like about the Duratracs is I lost a good chunk of MPG. And they don't seem to be as good in the cornering and track as straight. But traction is way better.
