The harbor freight trailers come with added cost of registering, licencing and insuring a trailer, whereas a two inch receiver hitch mount jobbie isn't classed as a trailer, so no added fees.
I wasn't dissing the trailer idea, it would definitely come in handy for other chores in addition to hauling the bike around. I'm quite comfortable pulling a trailer myself. Hope to pick up a Ural with one someday.
They make wheel chocks you can bolt to the trailer floor so the bike doesn't go through the back bumper:................
These have been marketed under various names/manufacturers since well before I started riding in the late '60's. Not my first choice. Keep the speed below 50. No matter how well tied down, a big bump can turn it on its side. It is next to impossible to back up. The short turning radius will jackknife way too easily. REMOVE THE CHAIN. A bump can cause it to shift into gear or a jerk at a gas station will pop it into gear or the chain will pop off. I have seen tires and transmissions destroyed like this.
