2002 Shasta Revere 290

I know - Shasta, right? We just bought it this summer and have only had it out once so far but like it very much. Trouble is we know very little about it. Took me way longer than it should have to find the water heater bypass, for example. The "owners manual" is as useful as those for other rigs, which is to say, not much. Anyway, thought I'd toss out a line to this group to see if anyone has one, had one or knows where I could find any more literature on it.

Thanks for any light you can shed.
