To put that in perspective. My trailer has a 12'-8" deck. The sides are 14" tall down the sides, 20" tall at the front. There is 10" of platform past the front wall. The Tongue Jack is back in front of the platform that the tongue goes under. Tandem 5200 lb axles with brakes on both. It has a recessed tool box in the back that you drive over. It has a 50 gallon water tank between the axles under the deck and a self container water pump that runs off of the trailer battery that runs the electric tongue jack. The tail gate is 4' long, full width that locks with a vertical horse trailer door latch run horizontally. The tail gate raises and lowers with one hand since I built a load helper to balance it out with captured garage door springs, some cable and a pulley or two.
When we go out to the desert for 9-10 days at a time, we load firewood under the rear of the rig all the way back to the tail gate. Camp chairs, spare tire, Co2 tank, folding trash barrel, fake grass mat for the camper exit, box of tinder and girl scout juice, 4 6 gallon gas cans, and some odds and ends go under the rig and are never tied down. Just toss it in there and go.
The tongue box holds spare bits, coily cord connectors, some tools, hitch bits, draw bars for the hitch and some tire changing tools with enough room to store all the tie down straps.
The internal drive over wheel wells have doors that flip down to the inside. In those are spare fluids, spare driveshafts for the rig, belts, coolant, and other odds and ends but hardly full.
By all assessments, it would be considered a very small trailer since the tail gate closes almost against the rear bumper with the front tires against the inside of the front wall. The rig would not fit inside on the deck if the bumper did not go over the front wall.
