The clean-out plug should be near the end of the spark arrestor. Try <https://seafoamworks.com/product/deep-creep-penetrating-oil/> To loosen it. After it is out - try to keep it from rusting back in with copper based anti-seize.

If you run always run your coach's generator at 50% load or greater the answer is: probably not. That said, it is so easy to open it up after you change the oil and let the carbon blow-out, why not do it?

At initial build and install they failed to tighten the nuts on the wire to switch and after a thousand miles or so they shook lose and actually did some arching and tripped the switch to off inside the switch so the generator could deliver no power to it but shore power did. There was some significant burn marks inside the transfer switch box, we were lucky it didn't catch on fire and burn the RV up. I had a mobile repair guy come out to our campsite and replace the switch with a much higher quality one and Thor reimbursed me.
Same thing happened to us.

Yep that's exactly what it looked like. Just plain poor construction. Problem is they all have it and those that don't will after bouncing down the road awhile. :-)
