I guess I don't follow?
What are you concerned with as far as doing something that takes a lot of strength with a TT?
I have had TT all my life and there is nothing that takes strength to hook or unhook. Well, I guess jacking takes strength but I have had an electric jack for over 20 years so that leaves that out.
The WD bars may weigh 3 or so lbs a piece and it takes a little strength to lift them and put them in place but not and big strength.
When I have done 5 wheels the big strength move is pulling the latch bar. That thing can get really stuck sometimes and it takes a lot of strength to pull it.
Tell me what you are concerned with and maybe I can give you a better answer.
