You did exactly what I did for under the seat storage in the spring. Unfortunatly mine is still in the cardboard stage. Just No time to finish yet. I'm making mine sealed so it will stay dry, just bendin a extra lip with the pan break and using thin door seal. Trying to decide on a latch, thinking of using the ones I use on truck boxs I make, glove friendly. I hope to have this finished just after New Year. Have snow and need to ride, just need to find someone to ride with, locally, getting tired of going out alone. Walked 7 miles once on my old polaris.
