Even with the new wood there was still significant sagging of the cabover, especially when loaded. Before re-attaching the aluminum skin we also installed strapping between the main body and cabover section to really cement things in place. I am pleased to report that the front end is VERY solid now, I would recommend this modification to anyone who has the upper aluminum trim off of the lower body. Below are pictures from one side though this was installed on both.
The steel strapping came from our local hardware store and is impressively strong at about 1/8" thick. The strapping had to be notched to clear the roof lift and I secured it in place using flat head SS phillips screws that recessed perfectly into the perforations. I did pre-drill the screw holes so that the camper framing did not split due to the large diameter hardware.
