How to tow an early A?
I didn't mention that on the cross-country trip, before resuming 4 days later, I switched to a tow dolly so my wife wouldn't have to tow the trailer (repaired). I thought of renting one in CA, but U-haul wanted $350 (1994 dollars) since everyone was leaving the state. Once in AZ, I was able to rent a dolly for $120.
I reversed tow cars. I put the drive-shaft back in the Dart and put the Aries on the dolly since FWD. Some people can figure why I was using the FWD to tow-bar the RWD, and I know the Dart was slightly heavier than the Aries, but it worked fine. The tow dolly works fine on the interstate. You have to watch it's width on local roads, and it doesn't ride well unloaded. With a tow dolly, you can backup a little bit, which you can't do with a tow-bar. Personally, I don't like towing anything. It is un-nerving having something behind you rattling and trying to move your vehicle.
Re brake controller, all I did on that trip was hook the electric brakes directly to the Newport's brake light, with no controller box. When I slightly pushed the brakes, I got full-on from the trailer. That is a stable situation and was fairly mild. I wouldn't use it on mountain roads since you would over-heat the e-brakes, but on the interstate drive I used the brakes about 4 times per day. I have a camping trailer I tow with my T&C. I got a brake controller. I didn't want to hack up the wiring, so for now I just use it in full-manual mode (until I get the right connectors to elegantly connect to the T&C wiring). I set it on the console and press the red button when I want to brake the trailer, like going down steep grades or for rapid stops. You can adjust the braking level. My trailer is only 2700 lbs, so works fine.
