...because I usually wear my BH.
I forever take my BH on and off in the summer. Usually, though, if I need to move my trailer, I'm doing something that involves my BH. Murphy is a real wiener like that.
Anyhow, this is how I worked through the dilemma. I like my FEL the way it is and didn't want more holes sprouting out of it. Plus, I've moved a 10k trailer around when loaded with 3,000# of yard waste...you start reaching the limits of the FEL very quickly.
The arragement I have pictured has worked pretty well. Not a perfect solution, but there really isn't one to meet all needs. This allows me to work with the trailer and BH, which is what I wanted. When I get serious about towing my trailer (Halloween hay rides and the like), I take the safer approach of my dedicated Leinbach Line 3PH 2" reciever used in tandem with my weight distributing hitch. Of course, the BH comes off for that to be used.
The trailer pictured is my old single-axle 3,500# capacity trailer. I now run a 8'x20' 10k capacity dual-axle dovetail and pull it without any problem, even moderately loaded.
Hope this gives you another idea.
