I'm not sure how many inches are left. I need to measure that as you're not the first person who's wondering if the trays still fit. Some people say they do, others say no and then a few say one side fits but not the other. Go figure . I am not sure on depth of your trays but we have the Exile ball fenders and I probably have them inflated to 17-18" and they still fit in there with bags full.
