Yeah, I'm not expecting any of these trailers to pass an FAA inspection but I have been comparing the quality between brands. For the price that they are asking for these units comparatively to other types of recreational vehicles like boats I'd say the quality matches the prices.
I'm still kind of hung up on the whole tandem axle thing though. I used to have a 19 foot boat that weighed similar to what these trailers do and had two blow outs with that. The tires on that trailer weren't even tow rated so the dealer had to eat the cost for those. The boat didn't sway when it happened either, just dropped to the ground and it was noticeable in the cab. Drug it off to the side of the road and changed it.
My new boat has a tandem axle trailer and I've had blow outs with it as well however you can go further with that second tire supporting the weight.
I do think that if you put good quality tires on a single axle trailer then you should be fine. I guess that's something I need to check.
