Thinking about plans for 2023, and how I'd like to be able to take two bikes to the track in case one of them develops trouble. Have had plenty of success with single-bike U-Haul towing before, would be nice if it turns out there is a configuration that would work well with two. Or alternatively, another place to rent flat or enclosed trailers from that will carry two bikes. Any thoughts/suggestions, aside from buying my own trailer?
