My only comment regarding the Georgia manufactured trailers is, it appears by what I have seen at the race tracks I frequent, they appear to be manufactured for a low-end price point. Most of them I have seen use a sprung axle instead of a Torflex axle, the aluminum is more wrinkled (--which likely means the infrastructure is flexing) and the thickness of each component is less (frame rails, aluminum sheeting, plywood, etc.)
I suspect you can pay an upcharge and get the better axles, added door hinges with grease fittings, .030 aluminum siding instead of .050, stronger rear door, US-manufactured couplings, and better quality lighting.
I would assume Elkhart, IN trailer manufacturers have found themselves needing to compete against the GA manufacturers, thus they likely offer a cheaper trailer too. I have seen a lot of my customers purchase trailers throughout the years, and I have never heard any of them complain because they chose one of the better quality manufactured ones. Naturally, if the budget does not afford one of the better ones, then make due with what you can afford.
