Fiberglass resin would be my fix there.
Same thing where the cab has a big chunk missing.
Stronger than Bondo.
I would cut the broken pieces out and add a couple new pieces of wood glued into the pieces you cut out, then fill with bondo or wood epoxy sand and paint.

i would go this route also
You have such narrow sections there it appears that whatever you do is prone to breaking away. I favour Vids approach because I think it is simpler and after painting less conspicuous but I would first put 3 or 4 pins into the sections so that the resin is not relying solely for its bond strength for retention if bumped.

Never used fiberglass. I am sure a google search would help here, but do you or Vid have any good vids or instructions? What do you mean by pins - nails?
You can drill some holes to give the 'glass more tooth, or indeed use small nails (if you can drive them in without breaking more wood.
I'd make a form on each side of the break with some aluminum flashing (or whatever semi-flexible junk you have in the garage), to contain the resin.
It will get very warm as it hardens.
Peel away your form, sand and paint.

Thanks Vid - not to sound dense, understand all except that with the form in place, how will I get the glass in place - or do I do that before I put the flashing form up? Appreciate the patience.
The resin has the consistency of very thick syrup, so you need a way to contain it so you don't have to do a lot of sanding.
Put your forms in place, pour in your resin.
If you were doing a structural repair, like a cabinet corner, you would add some chopped fiberglass to the resin, but for the backbox, not necessary.

Ahhh! Makes perfect sense now. Any particular brand of resin you would recommend?
