I'm in the same boat. I did the same searching and eventually found someone that had frenched a receiver hitch into the upper portion of the BFH and reconstructed something of a crossmember behind the bumper to support it. I just tried to track it down as I thought I'd saved it but can't find it. I've held off doing anything because I don't want to fabricate a receiver only to have it interfere with the EvoLever when it goes in so I'll likely have both of those done at the same time sometime over the summer.
Only other option I've seen is the Crawler Conceptz version of the BFH that does have a receiver hitch built in. No clue how it's supported or what its rated for. Think its called the Skinny Series or something like that. I didn't like it because the receiver is built into the lower half of the bumper, which seems to defeat the purpose of the design in some ways.
