The only down side of of using a hitch mounted winch is the rating of the front receiver. My receiver mounted winch carrier is rated for 8k or 10k lbs (even though it will accept a larger winch) - It may be hard finding one strong enough for your application.
At some point, I want a heavier front bumper with integrated receiver but at this time just have winch access from the rear receiver. For my expected light duty extraction use, I prefer keeping the winch stowed inside until needed instead of exposed constantly to the elements. I carry two pulley blocks with me so I can redirect or double up the line. Although I have tested my setup, I have not had to put it into actual use. My biggest concern is an anchor point that is sufficiently strong enough to actually recover my vehicle when trees or other large vehicles are not nearby.
