I don't think the crimp connections are a problem. As bad as the polybutelene horror is, even after 20 years, the only reason my water system developed a leak was because the rubber washer in the fitting at the water pump failed. The crimp connections, even on that PB, haven't leaked yet. And we regularly tow on miserable roads. It's always a bit of a game to find where our dinette chairs are going to be when we open the door.
I think the argument against the Sharkbite is that they add weight, which could stress the pipe.
There are plenty of theoretical arguments both ways, but I haven't seen anyone mention an actual, water-to-clean-up problem. I tend to watch these threads because I know someday I'm going to have to redo ours completely, and I want to make the right decision.
