I would like to change my oil in my Generator but can not find the Drain Plug. It is an Onan 4000. I have a 2006 Fleetwood 29v if this helps..

Mine was under a cover on the bottom of the unit. I had to search for a while to see it. The cover is held in place by 2 square head screws. I removed one and loosened the second to swivel the cover out of the way to gain access to the drain plug. Hope this helps.

That is the exact cover I meant. Good find on the video.

Lets talk about the two screws . yours are square head.. I am not sure if mine are star type.. I trired I think it is called a T-30 but I wasn't sure. I couldn't budge the screws.. I didn't get under it I just felt it with my hand and then tried using the star. Again i am not sure it was a star. it seemed to fit but it was late and I didn't want to strip it... sheet metal bolts would have been nicer.. I think what you are saying is you have square screw heads..

I was able to remove the screws with a small square head bit. I will have to check again what the pattern actually is. They were a complete PITA to remove while worrying the whole time that I was going to strip one. Why they are torqued in so much I don't understand. I ran some thread lock in (light duty) so they can be removed with a little force but not back out while bumping down the road.
