Hi all- I just brought home a new (to me) 1995 Rockwood 1640. Very plain little camper. I like it. It has a Magnetek 6406 power center. It's frelled. I'm looking at the Parallax 6730 and a WFCO 8955. I know the 6730 will be a direct replacement as far as size goes. I'm not finding a cut out dimension on the WFCO unit. I don't imagnine that it would be bigger, and smaller isn't a problem as I'm a carpenter with access to a disgustingly expensice CNC router. the camper only needs the 12V for 2 small lights that I'm going to upgrade to LED's and the heater. Perhaps the water pump if it has a demand system like my boat, I haven't looked that far yet. The WFCO is attractive to me for a couple of reasons. First of all, the excess power availability would be enough to run the heater, the lights, and a 100 watt amateur radio and laptop. Secondly, it claims to be filtered so as to not generate RFI. I can see the pros to installing the WFCO, including the price for which I can get one. Can anyone think of any cons or issues that I need to be aware of that I'm just not seeing? Thanks for the assist.
