Well, with 'life and work' issues covered (not to mention figuring out how to get the camera going again), I got to building.
First up was the frame and front end (yeah, I was going to start on the cargo box, but this turned out the way to go).

The frame is one piece, which makes it nice. There was minimal clean up done other than clearing the resin over-fill between the spring suspension and frame.
There's not a lot to be wary of other than the cargo bed support rails. They're a bit on the thick side, and I realized this after they were glued on. Were it to be done again, I'd seriously consider using some Evergreen sheet stock (and the resin parts as the template) and make them about 1mm longer. The cargo bed seems a tad short in relation to these rails (I added a thin strip to fix this - seen in the picture below).
For the front end parts (engine compartment, firewall, cabin, and seat), it's all about dry fitting for position and alignment. No issues at all with fit or size, just double check their alignment. Oh, start with the cab base, then firewall then engine compartment. Things align off the cab.
The cab roof was easy to remove, but there's a fair amount of sanding along the back side to blend that with the edges.
The underside was next:

There are, at the moment, only the two parts attached at the rear. No worries here other than ensuring that the crossmember is straight.
