My
Escape 17 was one of the first built with dual
propane, the storage box, and an electric tongue jack. The Camco propane cover was so tight that it was difficult to open & close the storage box.
Since I've done quite a bit of Vacuum forming prior to retiring, I used the same technique to "flatten" the back side of the cover. After removing the cover, I used both a 1500 watt electric heater (inside) and a heat gun outside to soften the plastic, then pressed it against a flat surface. There was plenty of room inside the cover to still fit the tanks after flattening about 3/4" at the top rear.
Don't know if this would solve your problem, but it worked for me...
