I have put the kegs up w/ the pump to "index" the positions of the kegs with the pump so that after the lines are run, the plumbing will line up with the kegs.  Note that the LP gas tank is not on the cart, but on the other side.

Wheels are on!  I don't like them too much - they're lawnmower wheels... but I don't intend to do laps with the rig either!

Here is the sparge head and the lautering manifold.  The lautering head height will be adjustable via a clamp (I think).  There a holes drilled on the side facing the driveway...

I also managed to paint the driveway blue from over-spray.
