It's okay to be paranoid, but only when it comes to water leaks in an RV. :)
You could go to HD or hardware store and buy a pressure gauge and a few fittings. With a compressor you could charge the entire system to say 50 psi and let it sit for a day or two and periodically check the gauge. It should not drop over a day or two. This is the only way to know for sure and it's how piping system in new houses get tested.
If you did happen to have a problem, the PEX piping will be okay and it'd be a fitting, valve or faucet (or pump if it had water in it) that could be damaged.
'Course, make sure the fittings for testing you put together don't leak, lol.
THIS is the way to do it although I would suggest using a bit less air pressure, I tend to do this at 25 lbs to 30 lbs..
The reason to test with air is if you truly have a bad leak air makes no MESS but you WILL HEAR the air leak. If you have a minor leak you will still hear the leak but it won't be as loud..
After the air check passes then I CAREFULLY apply water pressure from my house (garden hose sprayer with a hose thread works great for this so you can shut off the water quickly at any signs of a leak).
Learned that one the hard way in my first TT which was used and the previous owner conveniently "forgot" to tell me that it wasn't winterized :M and had water coming out of trailer wall bottom at the bathroom when I applied water from my house...
