Is there a specific reason that they are all plastic not metal/brass ?
See the picture attached, the hose that I bought at home depot has stainless steel screws at the end, and the screws attached to pump that is made of plastic.
Is there a concern there ? maybe stainless steel against plastic causes the plastic to break during vibration ? And that's why all RV pipes are made of plastic ?
Plastic pipes are the way most house plumbing is going. The DS & DIL house plumbing is very much like the RVs. All the valves are plastic on our house as well the faucets are metal though. Brass is made with lead so you will not see it in plumbing too much today when it is used for drinking water.
Plastic is less rigid as well it accepts vibration well. Our 1973 Terry had copper piping which at times was problematic.
