The 22 Luggage works will fit but it requires some artful articulation. The wing lockers are not as big as they seem. There is an oil kit box and all the engine covers, prop-exhaust covers and pitot covers. We kept several long umbrellas in the right wing locker, plus the right engine covers. Then goes your bag, then goes extra stock, liquor, cups, napkins and other stuff. The 22 inch Luggage works has to be put in the exact center and it needs to be pushed up under the lip of the forward cover in order to be able to get the cover closed. It will take you a while to be able to do it quickly but it does work. When you are finished there isn't enough room left for much of anything in either wing locker. The wing lockers are not from Beechcraft they are an STC. They work well but don't have as much room as you think and you need to make sure the latches make properly.
Your electronics will be fine. Watch out for shaving cream and other liquids in your shaving kit. Keep those in a plastic bag. The airplane will cruise in the low 30's on longer legs and it gets cold up there.
