Our biggest complaint about general maintenance on our RV is what should be a simple job of changing the oil. The drain plug is directly above the axle. We have tried using a funnel to reroute it around into a pan, placing the pan on the axle to drain into (you can imagine how that worked out) whatever you do the splatter is terrible and since your are working around the axle, you better have worn an old shirt because the oil will run down your arms. Now the filter is also directly above this same axle. Can not get it off without oil down your arms and splatters everywhere and the axle covered in old oil.
Then we have to deal with an oil fill that sits so tight up against the roof of the motor compartment, a can can not be tipped to empty. We use a funnel with a flexible tube to try to get the filling down lower, but never fails it overflows before we are done, as you can't see the actual fill of the funnel. You have to use your finger to feel with the oil get to close to the top.
After what seems to be hours of clean up of old oil off axle ourselves and the new oil which has dripped down the whole motor unit, we say never again. But we have to drive 40 miles to get an oil change and after a $200.00 bill, we say OH we can do this this time LOL
