i was planning on towing the airtsream the same way - it weighs 3800 lbs and shouldn't be an issue since the trooper is rated to tow up to 6000 lbs.
BUT i've never heard of brakes being in the lcoked position and trailer not being moveable if i don't have electric brake controller on my trooper?
The first thing to consider is whether you have a compatible trailer connector on your Trooper. Your Airstream likely has a seven-terminal connector that can be either the blade-type (modern) or a period pin-type connector - - either one will have seven terminals. Depending upon the actions of previous owners, your Airstream's connector may or may not be wired such that it would be compatible with a modern seven-terminal connector.
I have attached a copy of the seven-pin connector wiring schematic that was being utilized when you coach was built -- and it is definitely different than the current industry standard schematic
. There is no guarantee just how your coach's connector is wired so it is best to check it out utilizing a commercial tester or a test-light with 12-volt power source to determine the function of each wire in your coach's connector.
Based upon my experience retrieving Vintage Airstreams, you can almost count on having to adjust the wiring on the coach's connector and/or replace the connector such that it matches what is on your tow vehicle. Just plugging the coach's connector can result in any number of maladies one of which might include having the brakes applied continuously (if brake wire on connector corresponds to charge line on tow vheicle) or an of a number of odd reactions to inputs that you might not anticipate. It is always best to allow for sufficient time to sort out the connector wiring when retrieving a Vintage Airstream with unknown connector wiring.
Good luck with your mission!
P.S.: Something else to consider. The Airstream will likely have a significantly higher hitch weight than your boat trailer, and the profile presented to the wind will likely be somewhat different as well. My personal recommendation would be to be sure that you have a properly setup weight distributing hitch as well as a functioning brake controller prior to trying to tow the trailer any significant distance.
