Entrance door problem

[GORDON HUMMEL]

I, like many of you, have had the sticking door issue when the door is in the sun!
Recently I noticed the door skin was seperating from the frame on the jam side. The frame is what I would call a Z section, inside going to the left, jam side going out and outside going to the right, rear of coach. This outside edge is attached to the door skin with structual tape. I removed the tape on the lower portion of the door. It was seperated +/- 3/16". Now this lower section of the frame has bowed out toward the rear of the coach 1/8" @ the center of the bow. It is as if the foam pushed it out. I tried clamping this 26" section with 5 c clamps & a 1" piece of wood on the outside, but ended up with 4 small bows & the frame edge still 1/8" beyond the door skin edge.
At this point I am considering removing the inner door panel & removing the foam insulation so I can get the frame edge back in line with the door skin.
Any recomendations?
