Hopefully (fingers crossed) I am done. I did all that stuff from my first post (TREs, heims, ball joints, new tires, new battery, new battery terminals, greased everything etc) and the shakedown run went well. Keith helped me fix my air conditioner.
Sine then I have done a ton of little maintenance things like fluid and filter changes, plus I fixed a couple of leaks.
My CO2 tank is being hydro tested and refilled and I bought a new tool bag too.
