Also made use of the torque of the new breaker bar I got from Harbor Freight to apply some good ol’ brute force to loosen some stubborn bolts.
Some advice on tools and brute force. If your only tool is a hammer, treat everything as a nail and don't use brute force, get a bigger hammer
I usually bust my knuckles 5 times a week and that's with a mostly office based job🙈
As for knowledge and experience, if people never tried new stuff, we'd still living on trees without fire (I'm not sure about some Apalachian mountain monster hunters though). Maybe you find someone in your area who can help you working on the wagon, so you can learn from him/her.
I have a neighbour, young guy in the late 20's, master mechanic and specialized in V10 VW Diesel engines (Touareg, Phaeton). Even VW dealers won't touch these engines and send them to him and his 2-guy shop. He's a real genius in what he's doing, but when it comes to old analog stuff he comes around picking my old brain and I ask him when it comes to modern engines. I showed him how to work on carbs and sync the two Strombergs on the Volvo B20 in his boat.
Never stop asking questions and you'll never stop to learn.
And now, get your gloves dirty!
