Cummins Onan generator exhaust modification

I am having the same problem with my Bigfoot. I was considering putting on the "resonator" and re routing the exhaust. My first effort was enlarge the mounting holes slightly in the generator storage area and shift the unit 1/4" to prevent the exhaust tube from hitting the camper frame. I then made some vibration mounts out of high density foam, set the generator on those and reset the unit with large fender washers and rubber grommets. This has cut the vibration down to almost nothing. Could you please provide a photo of how you routed the exhaust under your unit and what you did for vibration on the exhaust tubing mounts.
