I bought a device that screws onto the quart of oil. Then you turn it off, position the neck in the filler hole and unscrew the part on it. Think I bought at Wally World. Not yhe easiest to get to, but this works
Get busy living or get busy dying. It's your choice!
I could not find a commercial oil fill funnel and tube long enough to reach the oil fill, so I used a piece of hose about 36" lg. with a funnel on the end. If you have another person to help hold the funnel it will be easier. I do not have anyone to help, so I tape the hose and funnel under the windshield wiper and onto the windshield.......higher is better to fill faster.
One of the fixes in the 2016 Axis (after many complaints) is a repositioning of the oil fill to the front of the engine where it is easily accessible. What a concept! In my 2014 Vegas, I could just reach the cap with two fingers on my left hand way in the back of the engine. I was always afraid that I would drop the cap and never be able to find it. It also looks like they dropped the starting battery low enough that you can get it out without cutting the coach apart... Duhhh!
