Art,
Can't answer for Foretravel, but since it is out of sight, I see two options:
1. Repair with fiberglass.
2. Make your own replacement. Use aluminum box beams for the "stand off" and either sheet FG or aluminum for the cover itself. The stand offs would be front and both sides, with the back being open as the vent.
I did this on our 1993 U240, which had no shield for keeping water and dirt out of the propane/diesel compartment.
