By the way, Kendon has two different models these days, the original, as shown in the OP's posting, and one with a wide ramp which "squats" as the bike is ridden up onto the trailer. Rails guide the front wheel into a very substantial chock, and hold the bike up while you attach tiedowns. It makes it possible for any cretin (me) to load and unload a heavy bike without assistance. Those looking for a new trailer, this version is well worth the extra money. Only thing wrong with mine is I bought a single bike trailer, and wish I had gotten one for two bikes.
My Hyundai Santa Fe, with a 2 liter turbo engine, will pull the trailer with a K1600GT at 80mph all day long, as if it wasn't even back there.
