Thanks very much for taking the time.. Resident truck aficionados, Mr. Roo and Dave. Appreciate the feedback.
The rear mesh is placed on the outside ...don’t know why I did this...but I’ll have to live with it now. No more late night modelling I guess
The passenger door handle is actually pointing downwards; its fixed point is on the upper side.
The image below is where I got the idea from, but I don’t know if its a modern modification. It looked cool, and it was something that I felt I can add to individualise the model.
