If you must use the ezlube... pump very slowly while the wheel is turning. I would just go. I don't like major maintenance right before a long trip.
^ This and it won't matter if it's a hand pump or pneumatic/electric gun. Either will push grease past the rear seal easily.
Look at a cutaway pic of an EZ lube spindle.
Spindle is gun drilled and then cross drilled at the rear bearing, so it deposits grease to the rear bearing (by the seal).
In theory it pushes the grease forward throughout the cavity between the hub and spindle.
In reality it can push out the back (seal) pretty easily.
If you must use, I wouldn't put more than 10-20 squirts in the EZ lube and then force some grease through the front bearing from the front.
Helps if the hubs/grease are warm and spinning wheel while pumping grease.
Packing the bearings manually is not difficult, just messy. That said, I've had many trailers that I've never taken apart. I just hit them with a little grease once in a while. Front and back like explained above.
