I'll be shopping for a new (or new-ish) truck shortly for pulling a medium size trailer or 5th wheel. It seems like the vast majority of 3/4 and 1 ton trucks around here are 4WD, with jut a few 2WD...
Unloading the wd bars does help, but I will still spin the back tires as I navigate a tight turn up a slight incline. In my case, the grass is almost always wet because it's almost always shaded and down slope from a neighbor's thoroughly watered yard.
