I've always run between 5 and 700 lbs of weight in the bed of my truck, have yet to put it in the Suped duty, but, I definatley need it, the tail end is hard to keep under control in town(won't see bare pavement in town until the spring) both under braking and cornering. Last winter, I bolted a 4x8 sheet of 3/4" steel down in the bed of my old F250, and let the bed fill with snow as usual, never had traction problems.
I try to use 4x4 as little as possible, not to prove anything, but, it's alot easier to get out of a 2 wheel slide than it is a 4, and, I find that turning in 4wd in the slippery stuff usually ends up with the front end sliding alot before it decides to turn due to the lack of a center differential. This may change with the Super Duty as the transfer case shifter is nowhere near as convently located as the one in my 86 is... Ah well, such as things are.
Before the misses lost the weight, I used to put her in the back of the truck in the winter (was not so bad if she dressed warm)......no, just kidding. I use 500 lbs of sandbags in the rear above the axle and tie them down to prevent sliding. I have a rubber mat on top of the bed liner and did not think the bags would slide much. If I braked hard (normally for a much smaller vehicle with a real small tail pipe that sounded funny) I noticed the bags would slide some. If I get in deeper snow (4" or more on road) I put it in 4WD and it works great. I was amazed how well it did in the snow. Good luck to you!
For convenience, a sheet of steel is hard to beat for weight. A bag or two of sand is always handy to have for those super icy conditions. I have, more than once, opened up the bag and spread the sand on the ice to help out a stuck gasser that was spinning his tires. I just tucked the sand bags in the corners between the fenders and tailgate, no problems till spring.
