I found a site that tells about how to pack bearings, how electric and
hydraulic surge brakes work and more. If you're interested, it's
http://www.championtrailers.com.

FWIW: they do have hydraulic surge brakes that don't function when
backing up. They call them "free backing" brakes.

There's a section on brake wiring, how it should be done, how to test
it, how the different kinds of controllers work, etc. Also, wiring
diagrams of the popular trailer connectors.

Dunno about you folks, but my favorite search engine is
http://www.askjeeves.com (orhttp://www.aj.com, same thing). I foundthe
link to Champion Trailers from
http://www.gwi.net/~spectrum/camping.html;some of you might enjoy that
site also.
