Pat, a suggestion if it's not too late. Use a maintenance free 12V starting battery for the genset. I didn't and the darn thing ran very low on water. I noticed it had not run that week and went to check on it. Lifted the lid and hit the manual crank and the battery blew up on me. Piece of plastic hit my glasses and chipped the lens. Also got hit with a little acid in the face, but got that rinsed right off with no damage. No one would have noticed anyway!

I replaced the battery with a maintenance free Optima. Had to modify the battery compartment a little to get it to fit.
