OK such drama.
Bridgeway just called back. There are 2 of them, but they are in New Jersey!
So, he gave me a number to call, and I have to order them directly from the other Cummins location in New Jersey, and have them shipped to me.
I was thinking if I ordered, they could get it in to their shop and I could just go over and pick it up.
It makes things so much more complicated when you happen to live in Canada!!! Having it shipped across the border is a nightmare involving far more cost than it's worth. You get nailed for taxes - federal and provincial, handling charges, duty if applicable, extra handling charges from the carrier and etc etc.
Well, I'm in no hurry for this, but since I was going to be at Camping World anyway getting my backup camera installed, I thought it might work out.
I'd like your thoughts on how effective this would be, and I may be able to have it shipped to friends in Ann Arbor.
thanks so much for your input!

I see there are other steps... a tripp something or other (Sorry forgot the term now) and one of those pipes that directs the exhaust up and over the RV for when you're parked.
As for the pipe this is what you are looking for:
GENTURI EXHAUST
but look around you may be able to find it cheaper online somewhere else...

Yep, that's the part, and yep, any reasonably good muffler shop can install it. They shouldn't need a lift with capacity to handle the RT; the tech can slide under your Dodge pretty easily to R&R the pipe.
A thought: the current angled end of your pipe maynot work with the Genturi. I think it's intended with pipes that come straight out. You might want to have them reconfigure your pipe's end, using the cut-out section. Here at least, that small pipe is darned hard to find. You may want 'til you get the Genturi to do the resonator install, so you can take it along for them to see.
And yes, it'll make a difference. Much of the fan and mechanical noise is absorbed by the genset's enclosure, and some more fails to get out from under due the van's bodywork and RT-added fiberglass.

Great to know, thanks Handbasket. And GoBlue, I did see that genturi in Walmart for cheaper.
thanks a bunch, I will order the resonator, then wait until I have the genturi, then my next dilemma will be to find someone to install it!
Should I go for the super trapp as well? and do it all at once... I didn't really understand from Rodger's write up on that trapp gizmo... is it something you only put on while the generator is running, like the genturi pipe?
Many thanks

Someone put me onto Dyer's RV online store - they had it, got it quickly and cost about $45.00 to install. Ron

What is the net result of adding the muffler?
Is the level of noise reduction worth the investment?
Did it change the interior noise level much?

That looks just like the one I had installed on mine by the local muffler shop. Don't expect a miracle re: the noise, but it does seem to change the intensity of the noise to a more tolerable level. Definitely a bit of an improvement for mine.

It's a resonator, not really a muffler. I don't recall anyone doing an actual db measurement on one before & after. In part, it'll depend on how much your generator is shouded by the van's bodywork, assuming it's hung underfloor. The fan / mechanical part of the noise will be not changed, and the van's body effects that. Judging strictly by ear, it worked better on my '02 Chevy RT (low and well-shrouded) than on my Tiger (much higher, little shouding).
You'll have to be the judge of it's worth. Maybe $60-75 installed.
With the windows shut, very little. Getting the outer tailpipe mount 'right' helped that much more on the RT. It needs to be fairly free to shake with the generator. Also check all the Onan's mounting brackets to be sure none are in contact with the green part of the box. That can transmit some 'buzz' into the inside.

You can also get these resonators at Dyer's RV Supply (search for "onan resonator" on Ebay) $34.98 and $10.98 shipping. Their description is: Softens exhaust noise and can reduce sound levels in some installations up to one dB(A). Use with MicroLite/MicroQuiet, Marquis and Emerald gensets. Aluminized steel resonator mates with standard 1 1/2" (O.D.) exhaust pipe. Requires a 1-1/2" (38 MM) O.D. pipe clamp. Model number 155-2449 looks right

I'd suggest welding, since on most installations, it's under the living area. I'm probably being an old fuddy-duddy about this, but I trust a weld to contain gasses better, and to not come loose. Admittedly, there's normally almost zero back pressure in this area, but if you use a Genturi or similar, or a SuperTrapp, that changes a bit.
