While mounting an RV rated bike rack, I removed the stock (small) hitch receiver. As I unbolted it a whole lot of water came out the rectangular beam the 'U' bolts were attached to. It occurred to me that the holes at the top of the 'U' bolts are oversized, and the holes at the bottom were right-sized. The beam was full of water, and I couldn't see a weephole. This trapped water is a concern as I live in Boston and freezing weather is on the way. Thought I would let everyone know.
