As yet another care-giver, think about this: Put the grandkids to work! (Obviously depends on how old they are) When we had our trailer, I gave them all jobs once we got to the campground. Simple stuff like locate the trash-can(s) for the young ones, plug in for the older ones, collect firewood, etc. Made setting up much easier, especially after having to drive all day.
Oh, and even old hands screw up. Just today for example. In our new to us '94 Southwind there is a gizmo that looked like a soap dispenser. Could not get it apart to fill it so opened the cabinets to see what looks like plastic water-line connected to it. Trace it to the other side of the sink cabinet behind some drawers. Remove those to finally reveal the end of the plastic pipe which is hanging loose, i.e., not connected to anything. Also see what looks like a water filter that the end should connect to.
Now, I'm 57, do almost all of my own repairs, mechanical, electrical, plumbing, etc. I've put several weeks into fixing the plumbing on this MH so I know how it works. I also screwed in the water-hose to the city supply several days ago. So what do I do when I see this unused water-filter? You got it, I attempt to remove it. Water sprays everywhere, under the sink cabinet. I frantically try to re-fasten the filter so the water will stop while laughing my head off for being such a dummy and not thinking things through.
I succeeded in getting the filter back in place and stopping the flow but I know have the cabinets open and airing out......
