I forget the exact reason why I chose left side of aeroplane to crank jacks from. It may be it was flipped over and I made a mistake? Don't think it matters too much.
The area of fuse my dolly will be lifting from is about at a 8+1/2 degree to the ground. I took my best guess as to make the base of the main wheel mounts parallel to the ground (once the Mono tire is off the ground) so as to let the main dolly wheels freely castor so the fuse can be pushed sideways. The more of an angle the wheel mounts are from parallel to the ground, the harder it will be to get them to castor.
