What other things should I do to prep the trailer for my trip to Miami. Do these trailers have any sort of brakes ??
You have the basics of bearings, brakes, and tires in hand, and you may find the following helpful in regard to the wires and their functions as found with your '66 Ambassador: Umbilical Wiring Diagram -- 1966-1980 Airstreams
The above link has wiring diagrams as utilized on Vintage Airstreams . . . Airstream did not utilize the current industry standard 7-pole wiring schematic until fairly recently. The biggest value to these diagrams is the identification of the function of each wire as they are not the same function/color relationship as is in use today.
The trailer brakes are probably Kelsey Hayes electric drum brakes, and you will need an electric trailer brake controller in your tow vehicle to insure that the brakes can be fully functional. I have been lucky with my retrievals in that the brakes and all other safety features functioned with little more than cleaning of the terminals on the trailer connector and re-wiring the connector to match my tow vehicle. You might find some helpful information in the article that I wrote describing some of what I have learned on Vintage Airstream retrieval expeditions at this link
Good luck with your Airstream!
P.S.: While boat trailers rarely utilize weight distribution hitches from what I have observed, you will find that your tow home will be much smoother if you utilize a weight distributing hitch for the tow home. Use of a weight distributing hitch is particularly important if the weight of the Airstream approached the maximum that your tow vehicle can tow.
