Frame Connectors - install question

Yea, now you guys got me thinking and I'm prolly going to lose sleep because I'm Arguing with myself how I'm going to do the next car.

This thread is very timely, because I'm about to do connectors on my valiant wagon.
I am sure either way is fine. That wagon has shorter doors and a lot more bracing because of the door jambs etc. Pretty stiff structure.
