Our Mh is a pain to fill with propane. The bay door swings up. If close to the curb at Flyin J you have to practically crawl under to connect the hose.
So I always try to be out as the lane allows to the other side. The door would hit the slide when open if you tried to fill with propane but who opens the slides when fueling.
A different door prop is order.
When we were in Az two years ago it was cold much of the time. Used quite a bit of propane. They didn't have anyone that came around to fill the propane. We top off whenever we can. No need in taking a chance of running low.
