On the web I have seen generaly 4 types of 4 doors.
Below will be my old school photoshop & real pictures of rigs or new school photoshop pics.
Im just playing with the look. Next is to figure out what wheel base these would be?
Full size rear squared door. This is really long 90" plus the width of a full door.
Full size rear 60 degree cut.
3/4 size rear square cut.
3/4 size rear with 60* degree cut.
Original pic if you want to really do your own photoshop. Enjoy!
Here are some photoshoped rigs. The first is the original photo.
