Most Onan gennies installed on fifth wheels are vented through the floor but they are typically 5.5 Onan units. We have a TH with a 4K Onan installed and it is vented through the door, can't help on where to store gas as our rig has a 25 gallon tank for genny fuel.
Obviously gas consumption on such a large genny will be significant, but I would imagine running both ACs will require roughly 5K watts and consume about a gallon an hour. Our 4K unit uses about a 1/2 gallon depending on load.
Can't help you on installation as ours was installed at factory, but if you got a good deal on your Onan and you already have the prep done from the factory, it might be a good idea to have it professionally installed to eliminate any guesswork. Our Onan utilizes our house battery bank for starting. Good luck and enjoy the convenience of an onboard genny.
