This, less the additional nearly 20-ft of 3" air piping required to get from the turbo to the cooler then from the cooler upwards then across the roof of the engine house to air intake horn, is what I ended up with. I had to lower the original Onan mounts to make clearance for the Yammy that would live above it. Then last summer, on our inaugural 'First Trip' post-swap (yeah-yeah... the one where I got 'towed' home behind a Kenworth) that: PORTABLE GENERATORS ARE NOT SUITABLE FOR FIXED INSTALLS IN THE CRAMPED CONFINES OF AN RV ENGINE HOUSE! It simply got too hot while running in there and I shut it down after 10 mins, and resolved to rip it out and find another solution... which led to my next faux pas. I sold the Yammy and bought me a low-hour (300-ish) Honda air-cooled EV4000 with a remote start kit and muffler that could be mounted in an enclosed compartment with both the engine exhaust pipe and fan forced coolant air exiting THE BOTTOM OF THE ENCLOSURE. This is important!
