Motorcycle Camping Trailers

Im thinking of building one to pull behind a 150cc scooter to carry camping equipment. I think it would be better to follow as a drawing of a wheel, similar to the old Cushman scooters and drawings. Any help would be greatly appreciated.

I saw the trailer with single wheels pulled behind golden wings. The coupling is designed as a joint U.
With all the weight being on the front wheel of the trailer is extremely stable /
I've never seen an unhitched and parked like a two-wheel, though.

What prevents him from training wheels on .... fall?

Both wheels are for the stability of your load, allowing you to better
Control your bike, plus the ability to carry more than if you had an installation of a wheel.

when you go into a curve which is the single wheel trailer will do? you lean your bike into the curve - what will tip the trailer? you'll have some sort of semi-rigid - articulated connection? I think you need 2 wheels for stability and flexibility.
