I have been rebuilding my 73 23 footer. The original water piping was copper and wandered up over the ceiling and all over. To replace I felt that PEX would be best. However PEX does not bend around tight corners very well so one needs to use lots of joints with the "shark" connections. From experience I knew that if there was to be any breakage it would be at a joint, more joints more opportunity for a failure. My solution....... use a flexible reinforced plastic pipe with every fixture connected directly to a manifold, one for hot and one for cold. No joints except at the manifold and at the fixture. (Some call this home run plumbing) Made sure that the 2 manifolds were accessible and the clamp fittings all had their tightening threads easy to tighten.
Just my solution to plumbing in extremely tight spaces.

I used the same type of corner bracket when a soft 90 would work when I
replaced the water lines in The Pig with pex. Where a tight 90 was needed I
used 90 degree brass elbow and shark bite clamps from Home Depot. Worked
great every time and no waiting/ no leaks.

I used PEX but heated the pipe where it needed to be curved. Only used fittings where they were accessible.

I'm a real fan of Pex (I'm licensed to install it so am very familiar with it ). Although nothing is 'freeze proof', Pex is the closest thing you'll find to it in H20 systems. The fittings certainly won't survive freezing but the pipe will. You'll use fewer fittings in the installation which are the Achilles heal of any system. If you use an expandable tool the fittings are very reasonable and the best connection you can get. The tools come up used on EBay frequently for reasonable amounts ( bought a pair of the tools with dies for $75 on CL). There are different types of Pex, 'A' being the easiest to bend and if you do kink it a heat gun will remove the kink. Here's one of the tools listed now:

Had an older travel trailer with cpvc plumbing in it. In an area with
freezing weather it truly sucked. When it freezes it splits for great
distances. While cheap and easy to mend when access is available often I
had to chase pipes into compartments where access was not easy. With pex
you can design your system with access to the joints and not sweat the runs
because the runs will not split when they freeze.

Of course winterizing the system would prevent this from occurring A but as
you know sh👎t happens. Also, some people like to use their camper in the
winter.

The "tools" consist of a clamping tool ($35) and learning to do it consists
of installing clamping tool over clamp/hose/fitting and squeezing. The ONLY
reason I piped up about this in the first place A is because you declared
that cpvc was the only way to go and I had enough trouble with it to decide
I would never purchase another rv with rigid plastic pipe. Wanted to spare
others of the potential frustration. So quit calling the kettle black.

The clamping tool is only one way to do it. The professional plumbers perfer to use PexA with an expansion collar and to use an expansion tool to expand the pex and the collar to fit it over the barbed fitting. The pex then shrinks back to tightly grip the fitting.
The expansion tool is more expensive but it does a better job.
It can also be rented at a tool rental place.

I am aware that there is I multitude of styles of pex type tubing fitting
and clamping systems. If I were to plumb a house filled with expensive
hardwoods/furniture and the plumbing would be costly to access later like
its buried in a wall covered with sheet rock and then cabinets I would
probably use copper since I have a lot of familiarity with it and will
outlast me but for the coach I used the "shark bite" tool and fittings
from Home Depot. All of the newer mh/camp trailers if have looked at
itelize a pex type piping material. My neighbor at our vacation place in
eastern Washington has a 5th wheel on his lot which he uses as a guest
house. It never moves and when I asked him about winterizing he said he
occasionally remembers to do it but has not ever had to fix the supply
lines. It can drop into the low twenties and stay there for over a week in
winter. The shark bite fittings are a bit spendy but there weren't very
many compared to plumbing a house. It was very easy to do and I did not
have to worry about spilling glue or primer while installing it. Also, when
I changed my mind about routing or length,no fittings were wasted because
the clamp is removable and the cheap pipe sacrificed. Red and blue coloring
made keeping hot and cold runs easy to identify. Not a single connection
leaked and I had never done it before. Not declaring this is the only way
to go and certainly not the cheapest if you only count materials.
