Looking for info on Onan Generator for Wolf Creek

Do any wolf creek or Arctic Fox owners have the Onan 2500 Lp generator? if so what holes did they cut in the bottom of the box for venting? I could use a picture of what the bottom looks like where the air vent lp vent and exhaust come out? Before i do any drilling or cutting i was gonna make a template first. Our Wolf creek was Generator ready and i have since purchased the generator but its up to me to cut all the vent holes. And it seems to me i would want some covers over these vent holes any help or pics would be great.
Thanks Todd

If you cant get the lengths/bends in a one piece simply 2. Manual shows both a straight or 90° connector available to adapt muffler to tail pipe, but doesnt show tail pipe extension.

Manual http://www.norwall.com/product_pdfs/626_2.5hgjbb.1121.pdf
• Exhaust kit elbow 90 degree (P/N A041H694)
• Exhaust kit downtube (P/N A041L816) 5.75" lg
Manaul shows the above which are flanged down tube connectors. With a straight down tube then add section with 90°.
However available 'kit' 155-2325 shows a split clamp on- what it doest show is if it clamps directly to gen or to downtubes above (which I suspect is case-extension clamped to bolt on down tube)?

Possibly if Onans are supplied by camper mfg-inquire to them for needed parts?

You might want to install the Onan resonator as part of the system. It will help with some of the noise. Im not sure of the part# but you should be able to Google it.
