Hi, OZ
Me being a "Boat" guy.( Building Boats) Its easy and if I don't like it I can just make something else.
Looked at Alum and Steel and just feel it can also be done with glass. Also was thinking it could be repaired easier in the field. But I maybe wrong ? Also been looking a other cores to use. But $$$ a sheet.
Will build some prototype boxes and see how it goes. The cool part will be how they mount. They all will be able to be removed if needed. On the semi they are very hard to remove. Won't do that again.
Any body try using a split A/C unit with a 2K genset ? I have 16.7 amp's and some of the 115V systems are listed at 15 amp's. I can go to the 3K (cheep ***) but I have a 2K and like it.
