Why virtually no single axle 5,000 lb GVWR cargo trailers

[Tractorable]

I have a single axle 7’ x 14’ PJ utility trailer with a 5200lb axle. It doesn’t have brakes so it’s legally limited to 3500lbs total weight in the state of Virginia. If I installed brakes then I’d have to get it inspected every year. So far I haven’t had a need to carry that much weight but the option is there to do it if I want to. My truck has a 5000lb towing capacity so I’m happy staying below that limit. Mostly use it to haul brush and logs and bulky objects that don’t fit in the truck.
