@wavshrdr Thx for the link the TW trailers ... if they only made them in aluminum instead of steel.
I second wav's comments on the single wheel design. If high speed maneuverability, single-track, or rough terrain are in the picture, the single wheel design wins hands down. However, when loaded, single wheel trailers are a handful when stopping and parking. I don't have kickstands on my bikes, so getting the rig into and out of an "L" is a dance.
