I don't know what your van is like, but I think they're essential for towing. It depends on whether you've got an aftermarket bumper, and how it's attached, but having a tow point up front is a necessity for offroading in two or four wheel drive. Many front bumpers are held on with a few relatively wimpy bolts and have poor attachment points. Front tow hooks are often pretty useless as well (and I have a couple; not good for serious stuff).
So I'm a huge fan of having a receiver up front, if installed correctly to handle this kind of work. Lots of bolt-ons don't fit, or are so hard to install that you might as well weld one on, or have someone do it. Properly constructed, it braces the front frame rails and provides a tow point you could hang the van from, and that is relatively immune from damage due to side pull. And you can use it for racks, steps, etc. Right now I have my Hi Lift stuck in there.
I mounted a winch on top of the front hitch receiver; worked pretty well. Some photos:
