Hello Mike,
We too are 3575RL owners and really love it!
We recently moved into it as full timers.(3mo. ago). Mel is currently out to sea, so doesn't have access to the forum right now, but he is a Chief Engineer on a very large Tug and knows quite a bit about generators and such, so If you don't get your questions answered, give him a shout when he gets back around the 19th of July. Although with all the experience here on the forum, your very likely to know before he gets back. It's nice to hear about a fellow 3575r! Take Care
Joy
