FINISHED! Took me awhile to get back to the new install with traveling etc., but I'm pretty much 95% done. Just need to secure the exhaust pipe, route the aux propane inlet and secure the exterior panel to the camper.
My 2013 AF 990 required a totally new approach. First, the HGLAA Spec A (2500i LP) was slightly larger than the original Onan 2.5 KVD. The mounts didn't line up, and the brackets made it too wide to fit in width wise.
I built an aluminum rack sitting on shock absorbers to one raise it up for better front end air draw and two, to use the existing 3/8" mounting holes and three, to mount bolts up through the new rack into the bottom of the Generator tray.
Everything Onan/Cummins supplies is in Metrics. Either spend the extra time to check and recheck your conversions or just buy a metric tape measure for $15 on Amazon. I built a template to get the mounting holes through my rack drilled and sized before I set it in. I braced my large aluminum 1โx2โs with Z brackets and rivets where the bolts mounted to the bottom tray. I used 1/8โ thick 2โ wide strips to further support the structure. The generator engine is already superbly shock mounted inside the chassis so my aluminum rack with the shock absorbers was almost overkill. I also added some sound deadening material (KILMAT 80mil) inside the entire generator compartment to further cut down on cabin noise โ it worked. I mean the difference is unreal.
I have zero vibration into the frame โ unlike the old KVD - and the thing is SUPER QUIET. I mean itโs so quiet I intend to ditch the Honda 2000. I believe Onan advertises it meets the National Park regulation of 60db at 50 feet. At 50% load itโs 65Dba at 10 feet.
Overall, itโs a huge upgrade with dramatic improvement. The drawbacks are you have to custom install these into older campers but in my view the improvement in vibration, noise and sound is unbeatable. Be ready to spend some time checking and rechecking your custom mount โ I think I put it in two or three times to check for form fit and function โ itโs a beast at 110 pounds. Cost is always a negative and due to supply chain issues, I had to wait a few months for delivery. On the plus side, the thing is so quiet I intend to put the Honda 2000 on the shelf and leave the gas cans at home. That in itself is a huge win! Now, if it can be as reliable and easily maintained like the Hondaโs itโll be a keeper.

Is yours the new inverter model too?
Nope. ๐ I bought it back in Sept 2019.
I never heard the original one run. When I took it to get fixed it only had 202 hours on it and the stator had failed. I was told it needed a new stator, that is no longer available and a new rotor. There's a company in CA that would rebuilt my stator but it would take a few months to get it back. The repair would have cost me around $1500.
So with the generator being nearly 25 years old with only 202 hours on it and suffering from a major failure I opted for a new one.
I traded the old one in on the new one and they fixed my old one and sold it. When he sold it he got paid for the repair and he gave me the difference, just over $400. :B I thought that they treated me extremely fair. I'd recommend them to anyone one.
Here's my new one. I had an exhaust shop alter my old exhaust to work with this one.
The bottom of the enclosure for the generator is closed unlike the newer Lance campers (from what I've been told) which helps cut down on the noise level. Its quieter than my friends portable "quiet" generators.
I have 84 hours on this generator and I'm extremely happy with it. I do wish it was the new inverter generator though. ๐
