Depending on how you want to run the arrays the following post with x-sim simulations, based on actual impedance plots of single drivers might help you to make a choice between parallel-series or series-parallel wiring: http://www.diyaudio.com/forums/full-range/303417-range-tc9-line-array-cnc-cabinet-38.html#post5087837
The biggest difference is around the impedance peak, where parallel-series wiring has the advantage. More even load balancing between all drivers that way.
paralleling drivers and then place those groups in series would be my preference. Even though my own array is 5 drivers in series, 5 of those groups in parallel. As said, biggest difference will be around the impedance peak. lots of discussion in that thread about this subject slightly before and after that post.

Well, dang, conflicting opinions... From what I read of that thread, it really seems that the main advantages of the parallel-series arrangement is to be had in sealed shared volumes, and I’m planning on going open or semi-open baffle with these, so I shouldn’t run into the major backwave impulse issues that seemed to be causing the majority of those cone movement problems.
It's up to you, most impedance plots I've seen from series parallel wired arrays (including my own) have some sort of wiggle right around the impedance peak.
OPC's parallel-series wired array did not show this. This will probably still be true with your open or semi-open baffle wired array. It's your call, not much to lose here.

So 100 of these about $50
Putting 49 of these in a line array is 1,421mm edge to edge.
will fit in my enclosed trailer quite well.
sealed enclosure would work?

As high as the Qts is on these, the only realistic options are sealed/IB or OB. I’m planning on open baffle for mine, but sealed would be just as good if you didn’t want a dipolar response pattern.
