2x rear light groups (yellow indicator, red reflector, red stop/tail combo)
1 coupling (swivel type, since it’s to tow behind a motorcycle!)
Ask the RTA
Do they supply the Vehicle plate?
At what point to I get a VIN? Does the RTA put that on the build plate for me after inspecting? Do they even inspect, or is that only the inspection mob?
Does chain have to be welded? Or is bolted fine?
Other things to find out
Talk to eco-tec auto gas (My preferred vehicle inspection place – They’re VERY easy to deal with!) and find out if they can do a blue-slip on a home-built trailer.. RTA site says they just need to be a full AUVIS station, which they are..
