I wonder if the trailer will be too weight biased toward the rear and have too little tongue weight with the initial design, which would be bad.
In front you have 245/40-17 tire/wheel combo x4 probably weighs in about 46-48lbs ea.
In back you with full 5gal gas jugs are probably about 32lbs or so each x4, plus your bin with tools, spare parts, etc...rear weight can add up quick so you might need to take that into account.
I've built a couple harbor freight tire trailers over the years, so kinda been there done that
On the last trailer I built to hold a set of tires, large bin, plus 3 5gal jugs, I put the jugs in the middle. Seemed to balance well.
nice and creative design for sure
