I remove the grille after each trip and clean it. Then put back in the box and store in the forward basement compartment.
I also us Dryer sheets in all compartments and inside during storage.
No varmits to date, but had a cat in the engine compartment and scared me more then him when I opened the hood to check the oil.
What do others use for gas tanks, I carry a 20 pounder. Looking for other solutions, do not want to hook into LP line at the tank at this time.
