I noticed in HD the other day, a tool for crimping pex fittings that is only $25. I can't find it on their website, but it is a clamp-like device, with several size holes, for various sized fittings. not sure of the name for this type of tool...maybe a "die block". Anyway, the "squeeze" comes from your vice-grips. (don't know why the label said to use vice-grips, vs. any other type of pliers).
The interesting thing about it was that it looks to me like you could use this tool in the cramped spaces of an airstream. Thats what looks impractical, to me, about the standard crimp tools. not only are they expensive, there's no way you'd ever be able to use such a large tool, unless you were re-plumbing a completely gutted trailer.

Here, I found it:

Pex Crimpers
I saw this at the orange box as well, and would be interested to hear if anyone has used it successfully? For curiosity's sake of course, as I've already completed my re-plumbing using PEX and a combination of Flair-it and JACO fittings.

But if it works, then it would make using the crimped connectors VERY affordable, even for relatively small repair jobs.

You can rent the crimpers at HD (around $20/day) and I can also verify that getting those big tongs into position to crimp a particular fitting in a trailer can be very difficult. Mis-positioning of the crimpers leads to faulty crimps which leak, though the copper bands are cheap and relatively easy to cut off and give it another try.

Go with the PEX. I used the vinyl and it tends to need the clamps tightened now and then. Set it up so when you drain the system all fittings drain. They don't like to freeze. Should be a once and done. No fittings where you cann't get to them easily.

There are also fittings that do not require a special tool. Use compression.

I used PEX like most of the other posts, I messed up on my first fittings and went with Quest fittings. They were terrible. I spent the money and bought shark bites. I have had everything running for a year and no more leaks.

Buy the tool and go with the pex. It opens up options for routing your plumbing which can be a great advantage. Here's one of the pictures of one of my installs.
