Our older 2007 with no slide-out, the dinette benches do not have drawers. Phoenix introduced drawers a few years later. The drawer-less bench seats have full top and hinged side door access. Drawers make items easy to access, but it comes at a sacrifice to "volume" storage and with concern to heavy items.....a trade-off of sorts.
For over-all weight distribution, I store my heavy maintenance stuff such as the jack, tools, 20 & 30 amp extension cords in the front-most dinette bench....all rarely needed, rarely accessed. The rearward dinette bench stores our extra bottled water and canned soda. On top of those supplies, we store our dish washing trays & racks with easy daily side door access.
PC owners with dinette bench seats with drawers, but especially without drawers, have massive extra bulk storage. Model 2100 is the exception having the furnace in the rearward bench seat.
