Thanks for the picture! RV store, catalog item or your dealer can help you with this. Even Forest River but I would go through the dealer first.
I brought a new p-tank cover that had a lid. Someone was checking out the tank and didn't tighten the knobs for the lid. Upon arriving at the storage place I found the lid had flown off while traveling. I had an idea of where it might had happened. I went back and found the lid but clearly many semi trucks had ran over it on the 55 mph road. I didn't find the knobs that held the lid closed but the guy at the RV store called the manufactory and ordered the hardware for it.
Great choice for "Living within my means" and camping for one...
