We manage to get trucks around the yard in less than ideal conditions all the time.

If we need help getting it moving we'll either push it or pull it.     

For our short hauling tire chains are a real possibility.

You can also unhook the gooseneck trailer from the truck and use a ball on a tractor 3pt to move it around if it comes to that.

If you load out of a muddy pasture a lot then maybe it doesn't make sense but there are a lot of 3/4-1 ton pickups pulling trailers that never go off roading.

Unless you're talking about a big trailer it also isn't out of the question to hook the trailer to a half ton pickup for occassional light use.    Just use a little common sense.
