I was initially going to build a bumper. But I'm liking the behind bumper so much that I bought a steel hawse I'm going to have chromed and lose the big roller fairlead.
If you go behind the bumper you need to study the winch configurations. If you get the right winch(or make some concessions in your choice) you can do it with out really fabricating anything. You just need to cut an drill some heavy angle iron.
You can check out the mounting of mine if you weed through this thread.
