$500 math question on extending ball mount shank

All I can say is I've tried to remove lug nuts, bolts, etc with a standard length ratchet, wrench, whatever and if the nut don't turn, I slide a pipe in the end and dang, it takes the thing off without almost any effort...

Guess that's why the say, "give me a long enough lever, I can move the world.." or something to that effect..

I would think the same thing applies to extending a hitch?

It's all about leverage, so take it from there and do what you need to do..

Good luck!
