First post, but long-time lurker both before and after actually joining this forum. Don't know that I could adequately express how much of a difference sites like this one make for novices like me. Great sources of both information and confidence for making 'right' decisions. The ability to communicate collective experience is a game-changer. I don't own a PUP (yet), but I'm looking at a 2006 Fleetwood Bayside with a/c, furnace, fridge, etc. It comes with a 25 amp converter. I know quite a bit about history (particularly medieval England), but I don't know much at all about electricity. I've been searching this site and others, but after a time the information, helpful as it is in proper measure, eventually all turns into loud screeching noise. As I think through PUP ownership, one of the things I've not yet figured out is surge protection. I've concluded that I probably want something (I don't care that it may be cheaper to replace stuff than to purchase protection...I don't know that I necessarily agree that cost is the sole determinant, especially when you consider the inconvenience, lack of access, and time involved to have something fixed properly. Ounce of prevention, pound of cure, etc.) Looks like the Progressive PT30C would do what the consensus appears to be needs done. So, a basic question for starters: Is a 30 amp portable electrical management system the right piece of equipment for a PUP with a 25 amp converter? If so, can someone give me the Dr Seuss (i.e. very simple) version of why that's the case; for example, is it because of the type of power, as opposed to the amount being used? If not, can someone recommend the appropriate alternative? Thanks in advance for your assistance on this question, and thanks in general for all the value and learning' so far achieved. P.S. I had no idea what the answer was to the verification question, "In what U.S. State are the stars at night, big and bright?" Is that something one should already know? I had to Google it.
