Wheel Well Storage Ideas Needed

We have a different slide in camper and I have been doing some mods to make it livable for our travel style. We ended up with a more open floor plan but lost some inside storage. We gained access to all 4 wheel wells, only had access to two on the old camper, plus a small dry outside compartment. I have filled 3 of the wheel wells with the following: gray water container (no holding tank), blocking, fire cap, bucket of small wood chunks for fire cap, outside gas stove, extra propane, couple of small yellow dog lanterns with oil, water proof bucket with extra supplies of paper goods and such, collapsable rake and a jumper battery for back up power if we dry camp to long.

So we still have the large wheel well space on front passenger side. Problem is the access hole is fairly small (I may eventually try to find a door and make it larger) maybe 8"X14". Would be a long reach to the front of the compartment, somewhat bigger (longer) items could be worked into the space from the back access doors to the rear wheel wells. Things on my maybe list currently are extra food and drink (would need sealed containers that would fit through hole) and dirty laundry (not sure how to handle keeping them dry and have easy access to put in dirty clothes. Don't think I need an extra battery.

So what should I put in this space to save inside space?
