I spcifically bought the "squatty" 10-pound tank because it has the same base ring as the regular 20-pounder. I then bought a "base extender" from CW, added a plywood base to it and then bolted it down to a stow-bin floor, close to the forward wall.
I put a couple of hooks for bungee cords, but the extender holds the bottle so well, I haven't bothered to use them. Getting the bottle out is a bit tricky, but manageable.
We're going to ditch our behemoth Char-Broil and designate the Q-220 as the patio grill. We'll get a roll-around cart for it. We then plan on getting a Weber 120 for the RV, so it will fit in a stow-bin without having to take the lid on and off every time.
