1. The ventilation and combustion air intake is below the generator and is a 4 in round hole covered by a screen.
2. the generator portion of the box is completely encapsulated (as much as possible) in both a sound deadening material, and a composite sound barrier. The "exhaust box" is also deadened and sound insulated.
3. The aluminum truck box is about 10 degrees above ambient, the exhaust box runs at 160 deg F, on high power. The generator itself is about as cool as when it is running outside. The only thing I noticed is that you have to leave the cover open for about 20 minutes after you are done running, as the inside of the box does heat up if the generator stops running due to latent heat and no air flow.
4. There is 250 CFM (cubic feet per minute) flowing through the generator and out the exhaust, entirely due to the Honda's internal fan.
5. I have a locking 15 amp plug and an extended run hose at the rear of the box that allows a dedicated line to be run to the camper power inlet, and an external tank.
6. I have professional experience in both noise control and industrial ventilation, so I kinda know a bit about the subject.
7. The box also doubles as a security measure for the generator itself and the rest of the box is used for storage. The rack is the stock one with a 250 lb capacity that came with my VCross.
I know this is not for everyone, but I love doing mods and I like the idea of drycamping with a whisper quiet generator.
thanks for the details! Good job.
