Welcometo the group and hope it never needs "fixing" but most do and the more we each know, the easier that fix may be!
So I will send along some links to things that may help educate you on the RV or maybe let you find some parts---before they give trouble!
Parts to see where it may be and how to get to things?
Plumbing is always a wonderfull thing to study?
And wiring of course?
Beyond blowing your mind (sorry!) one big first thought is the way batteries running down is a frequent problem for the novice Rv folks. Watch them carefully and try not to let them run down while not being used as that is a major point for lots of folks . One big item is that there are battery cutoff switches-----which don't actually cutoff ALL
the drains and things go downhill if we don't work to avoid killing good batteries!
Why no RV year, make and floorplan on MY signature as we suggest for others?
I currently DO NOT have one!
