I've been checking dimensions for about two weeks now....as stated most 10 cf will fit with little to moderate shaving but the one I located, thanks to another's install, fits the dimensions perfectly. I've been looking at exhaust fans too...its seems possibly a couple of bilge fans might work the best especially if pulling in air from the current side vent blowing over the exterior coils and venting as usual at the top. Another quick question.... If I go to the trouble of having a separate pure sine wave inverter(my mh has a 2500 watt modified)...would there be anything wrong in running it through that dedicated inverter at all times? I figure it I'm at sites with hook up my in house inverter/charger would maintaining the battery bank(6-6 volt batteries)...just wondering?
