My B.O.B. trailer is about 8 years old , as you
can see the PIN holder broke out before it rusted, there is no way to fix this.
The trailer was always difficult to keep from
twisting when fully loaded. I recommend a two wheel trailer.
Or add a Kick stand!
Two wheeled trailers are more stable.

Trailer Building:
Here is one designed
by someone I know
|
ball joint for through bolt
No ball bearings on the hitch!
Looks like they went out of business. So here is
one I will have to build myself; But with two wheels under the center of the
load for better handling. But you can get it at sears for almost twice the
price:
When I was hauling a really heavy load down a not
steep hill. My trailer started pushing the bike and the front end started
vibrating side to side, out of control. I applied power to the pedals and it
stopped. Good thing it was not a steep hill.
A really heavy load on a trailer may
need a brake or two riding down a steep hill or just too much speed, so that
the trailer would not push the bicycle. But how would you attach one?
Cable brakes are certainly out as
connecting them would be a nightmare and I seriously doubt that a cable that
long would work effectively.
That means it's either going to be electric or hydraulic and then you would have to come up with a fool proof way to connect them without injecting air into the hydraulic lines.
Pneumatic I would guess would be out since you would have no way to create air-pressure to replenish a tank.
If you do succeed in adding them how do you apply them? A separate lever? That seems dicey.

a “surge brake system” would be
the thing to use.

the Surly trailer looks the best:
This is how a U joint should be built.
Make a yolk out of 1/8th inch x 1.5" stainless steel flat bar. Attached to a head tube.
