Thanks very much for the continued replies and advice.
I just went through jacking the trailer and inspecting/regreasing etc, each wheel. I am comfortable with that stuff, but didn't consider checking the electricals. It was only when I hooked up the trailer to the truck (brand new '22), that I discovered no brakes. And as electricals is not my strong suit, I sought advice from the forum. And I am learning a lot, so thanks for that.
I think next step will be, as others have advised, activate the breakaway system. Then go from there.
Having said that, My grand-daughter is about to arrive for a couple week visit and she demands my full attention, so the brakes will have to wait a bit. As we are driving her back home (BC to Denver) with the trailer, I will have to figure this stuff out prior to heading out.
Thanks again for all your help,
Marv
