You better back under the Sunnybrook and set it down on the hitch to see if your bondo busts before you paint it! That would be MY luck....lol. Looks great so far!
On a serious note, the left side looks much better from the outside, but both the inner and outer wheelhouse is gone, along with the rails/supports under the bed where it rests on the frame behind the wheel. The only thing holding the bed up in the center are the 5th wheel brackets. The frame is solid.
