Thanks for the advice about the batteries but I seem to have some other problem with them now, maybe a bad ground, going to work on them in about an hour or so.
Well sitting at the ocean now, just dropped and enjoying watching the surf and don't care about anything else.
Steve, I only use Idleaire for about 9 hours, when it is the hottest. The insulation I put in the sleeper makes a difference but I am not completely happy with it. at $1.85, 9 hours is reasonable to me.
