Do not slam or spam me on this, this is what I was told at this certain RV Repair Center.
May as well get in the soup with you on this one. Sharkbites are great for some applications, but when you have all of the jostling going on in an RV, I would not recommend them (note: crash helmet on for all the flack). I recently installed a reverse osmosis system that used shark bites and installed a pressure pump along with it. At least 4 of the connections leaked. And yes, the pipes were cut off square. If there was any side tension, they could leak. Research indicated the solution was compression fittings. Took the advice from more than one source and no more leaks.
I have used sharkbites under a residential kitchen sink with success. I was always concerned when when bumping the fittings. For the RV, I have used Pex fittings and a crimp tool-no leaks. But, I believe compression fittings would also do the job.
