Early last summer I installed the new Cummins Onan 2500i inverter generator in my AF 992. Later in the summer I added the Cummins Onan resonator
I did some sound comparisons with and without the resonator in this video
Without the resonator, If you are standing off to the side, at a 90 degree angle to the exhaust, you don't really hear the sputtering as much as you do if you are anywhere less than 90 degrees, and closer to the exhaust.
What I noticed after watching other videos on the resonator is that it makes an even bigger difference in noise reduction on the non inverter generator - the sputtering those make is pretty obnoxious.
If you have space to install the resonator and use your onboard genny a lot, it's a worthwhile upgrade.
Even without the resonator, the new inverter style gen is quieter than the generator I removed, as compared in this video sound test old vs new
My intention was to install the new gen in a TT I had, but I abruptly decided to sell the TT. I had already purchased the new gen, so I needed to put it to use. I decided to install it in the 992.
Before I installed the new gen, I installed some sound deadening mat in the gen compartment. Someone in the AF truck camper group recommended it.
Here's a short video describing that project: sound deadening mat in gen compartment

I wrapped my microlite with mineral wool insulation Of course leaving all areas where the air flows and exhaust areas. This made my generator on my class c incredibly quiet. Mineral wool does not burn until over 2000 degrees and does not mold or absorb water. Pack a little around your generator I think you would be pleasently suprised.

I'm glad you found a solution, but if I ran for an extended period of time, I'd buy a Honda. That being said, I don't have an issue at all with running my 16 year old Onan for 30min - 1 hr to top off my batteries.

I'm glad this is a "telling how" and not an "asking how" thread.

Solar. I don't have a genset and haven't plugged the camper in to the wall in several years.

I reckon that question was directed at the OP....

Yes, several things:
Last winter I installed a Pair of Battleborns. They charge faster than the original batteries.
I also installed 4 AWG cables between truck and camper back in 2010.
The last thing I did was install a Victron DC to DC Charger to compliment the heavy cables I added.
With this setup I can easily get 22 amps when driving. That's the most I've seen so far because all of my trips were short last year. The driving was done when the batteries were pretty well charged when I started the 4 hour trip there or back home.
