Almost certainly, if you have enough money on tap. The first comparable set I found is a water cooled Kubota gasoline engine, 15kW and cost about $13K.

First thing I see wrong. Is air exhaust has been cut in half. Shoving that much air into a small hole. Can create noise.

Not attempting to hijack this thread, but when I was a kid in the 60s, Mr. Softee ice cream trucks came around. You could hear the generator running in the back of the truck. Does anyone know what generator those trucks used?

I think that is the same truck that he later put a JC in.

That cooling air duct looks too small and that can cause overheating. I remember when I installed a 4BGE in my fifth wheel, Onan called for a certain square inch sized opening for outside air to enter the compartment. It was for proper cooling and combustion air. This calculation is different for each generator size. I second that a water cooled set will be MUCH more quiet than the JC.
Friends Don't Let Friends buy GENERAC generators.

Yeah, I was thinking the same thing.

But I question the accuracy of that list of *estimated* loads in the other thread. That's an incredible amount of refrigeration if they *actually* take that much power!
