Yes, life does have a way of changing our plans or making them really difficult.
One thing I do highly recommend is recognizing that we do need help. RV folks are so used to being out on the road and feeling they may need help , that many will be glad to jump in to try to lend a hand.
This group will do their best to sort any problems but if you are in a campground/RV park, there are likely folks very close that will be quite happy to assist. But we have to use some thoughts when we get stuck.
Maybe catching those folks who look like they've been at it for a while or have an RV somewhat like you and let them know you have a problem, can be a big start! Walk down to the office/ club room, etc and let them office folks know can be a starter. Most of us have been stuck needing help at times, so those old grey hairs can hide lots of good info!!
For online help, there are lots of Winnebago sites for info if you have a motorized RV. Far less for the trailer group.
But as a starter, the online manuals are often a place to start for info.
this site for the Winnebago home site can open lots of other info under the "owners" tab:
https://www.winnebago.com/
Then for plumbing specific info this can get drawings.

But step one has to be letting us know what you have, trailer? Motorhome? And then if you sort it down to a specific, we can hope to look for exact drawings, rather than guess at what is under the floor!
Standing by to help but we need more info?
Built in generator or portable? Assuming built in, there should be a switch somewhere on a monitor panel. Holding that switch is likely to make the generator turn over/crank and should start after a bit as a pretty simple operation.
If a motorhome and a manual onhand, it should give lots of good info.
A handy neighbor is highly recommended and most will be happy to help. Maybe some of this group is in the site just down the road? You never know till we check!!
Best wishes and hope to get you some help soon. See the info folks have at the bottom of the first two posts? That's what we need to get started!
