I got a portable vacuum and put it there. All the accessories are in bag stuffed into the void to the left. Stuck it in a small can koosie to snug it up.
I have only had it a couple weeks and have only had one day of rain. There was a little water toward the front of the bed after the one storm. If I had put in drain tubes It may have prevented that but im not really concerned with the little bit of water.
There ar tubes for drainage. I didn't set that up. I don't leve stuff in my bed. There was a little leakage without drainage tubes installed. My concern was just for short term storage if it happens to start raining and keep snow out of bed.
I was wanting a hard retractable cover but they were looking pretty expensive. I found this one online on ebay. I love it but the instructions are not the best. Watched the video like 20 times but was worth it. Delivered it ended up being $533.
