When I mentioned i wanted to buy the truck my bro said you dont know how to fix them, you dont have the space and you dont have the tools. I said thats what makes it all the more challenging.
Good for you! I'm thinking you're earning some bro respect
One way you can also check that each piston is up is carefully feeling for the top of it with a screwdriver (plugs removed).
Just another shadetree trick.
