Hi - I've never owned a truck or 4x4 before. I want to buy a 2008 F350 Diesel SRW Crew Cab Short Bed for a future 5th wheel (the truck will be sufficient for the 5er I have in mind). I've been obsessing about whether to get a 4x2 or 4x4. I will likely be a "fair weather camper". However, I may use the truck as my "daily driver". Although we don't get too much snow in southwest Indiana (right on Kentucky border), this brings me to several questions regarding the 4x2 versus 4x4 configuration with a limited slip rear differential:
1) Although I may have misunderstood something, I read on RV.net that only one wheel (not two) really is powered on a 4x2, whereas only two wheels (not four) really are powered on a 4x4. Is this true, and does this apply with or without limited slip? As I mentioned, I may have misunderstood something.
2) Is limited slip beneficial on BOTH 4x2's and 4x4's? I don't really understand how that feature works other than it is "smart" enough to power the wheel with the best available traction.
3) On a slippery road (but without any snow on it), I heard that 4x2 diesels are VERY front heavy (due to the heavy engine) and, thus, must be weighted down in the rear to be safe to drive with. Is this true and does this also apply also to 4x4 diesels? As I understand, 4x4's have more weight in the rear due to the transfer case, but I wasn't sure if that means I don't need to weight down a 4x4 in the rear also while traveling on slippery roads.
In other words, I'm trying to understand how much disadvantage I will have with a 4x2 versus 4x4 while traveling on slippery (but not snow covered) roads. I'd like to get a 4x2 since I'll likely be a "fair weather camper" and hear they get better mileage, ride better, sit lower and cost less to buy/maintain. However, since it will be a daily driver, I want to make sure that I won't be totally paralyzed in icy conditions which we usually only get once or twice per year.
