Ok to use flexible Pex for water lines in SMB?

I'm looking to update the water system a bit in my 98 SMB. My van came from SMB plumbed using rigid Pex water pipes. Last year I removed the sink to make room for a third captain's chair, and at that time also cut out the section of pipe from the pump to the sink. I'm going to reinstall the sink in a new cabinet, and may also add a shower wand at the rear doors at the same time (I had a thread on that a month or so ago).

The question: is there any reason not to use the flexible Pex water piping for the new runs? It's a lot easier to work with, especially on long runs. What does SMB use on more recent builds?

Also, looking at the SMB install, it's a mess of Pex pipes criss-crossing each other all over the place, taking up a lot of wasted space under the dinette. I may just go ahead and replumb all the visible hard Pex pipes with flexible.

Any thoughts or suggestions are most welcome.

Yep. Apollo Pex from Lowes works. Fittings, clamps, etc. will work. If you're going to do the whole van invest in their crimpers, which are 40 or 50 $ IIRC. It's worth it.
Currently vanless. Weird.
