Unique dingy seat/storage/6-gal fuel tank case-fits between pontoons and aft at transom. Low enough to not interfere with motor mounts and positions driver about where you would otherwise sit on pontoon holding tiller. Made of what appears to be thick polypropylene orange color. Top comes off across top for access and has two padded seat areas (one on each side). A regular 6 gallon plastic fuel tank will fit inside, out of the UV rays and catching the inevitable small fuel spill before it is awash under the dingy floors. Great unit to hold your other gear, a battery for lights, small cooler, clothing, etc. and interior stays dry while under way. Measurements 26" between pontoons, curved sides wrap around inside of pontoons and becomes 41" wide top/seats, 14" deep-fore-aft. Weighs about 16 # so shipping is cheap. Asking $115. You pay shipping or pick up in Houston TX area. Can forward more details and pics or questions: 281-383-2927
