Bikeman (and others) carry lots of rings in lots of different bolt circles.
On a side note: What possible reason do you have for carrying 100 pounds in a trailer and then adding more in panniers? Trim down your load! I pack heavy and even I don't lug around 100 lbs of stuff.
My tent and most of my other camping gear is heavy, and I cannot afford to buy lighter.
