I know, dumb question but going to ask anyway. I have a 2001 HR Endeavor 38 and wanting to change my oil. When I open the back door of the coach I see on the right a small sticker that says engine oil and I see two caps. One is has a bigger opening and the smaller one below it is the dip stick. I have opened the floor doors inside the coach to trace where these two pipes go. The bigger of the two (top one) seems to go into the top of the motor to what looks like a gear drive type cover and the other goes down into the block/pan. I'm not sure if this is the oil fill tube or maybe I should just fill from inside the coach where I see a oil cap on top of the motor. I know this sound silly but I can't seem to find any pics or info and what this bigger hose at the back of the coach goes to.
Thanks,
