If what your pulling in Reverse is light enough you wouldn't notice any issue with a 4wd truck. However, if it is stuck good or heavy you will not be happy pulling in reverse and when you turn the truck around you will be amazed at how easily the truck pulled it out. By pulling from the back it transfers a lot of weight to the back wheels making them more useful while still having the front wheels working with the weight of the engine and front end over it. Pulling in reverse lifts the weight off the rear wheels and puts it on the front effectively making your truck a front wheel drive truck as the back tires don't have much weight over them to help gain traction.
Tractors are similar but also have tires designed for pulling forward and they don't work as well pulling in reverse (this is why some combines with RWA have the rear wheels mounted "backwards", if they get into trouble the RWA pulls the correct way to back out of the trouble spot)
I pull from both directions all the time depending on what I need to pull and where I am pulling.
