Bigfoot RB21 Doorframe removal

[PrimitivePete]

I am looking for information on how to remove the entry door frame on an RB21 as mine is out of square and the entry door is rubbing on the lower sill on the latch side.
I want to get it square to give me enough clearance to mount a Liepert solid step.
If anyone has any info it would be greatly appreciated
Thanks in advance

Before you do a lot of work to get the door square, make sure the frame is still square. I had to rebuild the door on my 94 and the frame was not square so I rebuilt the door to match the existing frame.
