Service Point Locations Cummins Onan MDKBH Generator

Sorry about this, it's a sort of duh! question.
I have a 2019 RT-31 with the genny noted in the title above. I would like to service it for the first time (for me). However, I am having trouble finding some of the service point locations.
I have taken off the top of the sound shield and found the top of the oil dipstick. I took off the port side panel where the water coolant hose enters, but I'm not sure the water pump is down there. I don't want to unnecessarily take off any more of the sound shield without knowing which one to take off. The service manual shows a cutout on page 22, but it is not clear which cover to take off.
I hope someone who has done this can give me step by step instructions (starting with shield removal), particularly any tricks for what may be hard parts, like accessing and taking apart the water pump to change the impeller.
Thanks

I haven't serviced this generator, but earlier I found this YouTube channel where an owner recorded his dealer servicing the Onan Generator and the Volvo D4. Maybe this will help.

To access the generator to perform oil, fuel filter and impeller service you need to remove 3 panels. The top, the side panel and the rear panel as they are orientated on my 2011 R29. The rear panel is the panel where the fuel line enters and the positive and negative terminal is located. The rear panel is attached with 5 (I think) 10mm hex bolts. hope that helps. The service manual is pretty good at describing how to remove and replace the impeller. I replace the impeller every 2 years and the oil and fuel filters every year. If you go too long on the filters, they become very hard to remove. The first time I replace the fuel filer, I had to remove the fuel filter manifold from its mount and take it home and put it on a vice in order the remove the filter. I also replace the racor filter every year. Remember, there is an oil drain cock on the bottom of the generator to drain oil from the sump.

Thanks Bob.
Which side panel? The left or the right as you're looking at the front of the generator?
Where is the oil drain cock?
