Leave the cabinet door closed. It helps with sound reduction and yes to the Genturi. The Onan 5500 is designed for use in an enclosed cabinet and mine has never ever overheated even with both my a/c's running. The hot air exiting down from the Onan will turn green grass brown very quickly however.
I have the 5500 - unfortunately last summer I had both of my AC units going and the generator quit working and through a code. I could not get it started again that evening. I didn't even try the next day as we were packing up and heading home in the morning. I ended up having the dealer look at it and they got it working just fine again. They said it was most likely over heated but the built in failsafe turned it off before it could cause damage. I remember opening the compartment door and it was extremely HOT. I don't know if I'll ever run it again when its warm out without having the door open for extra cooling.
