Here's the problem i have with crap built in Texas.

One of the oldest tricks in the book is to build a manufacturing facility in a sparely populated area. That way you appear to be a savoir to the locals, but in reality you can tightly control working conditions because you just became the place where most of the community relies on to pay the bills. It's very hard to change jobs or even sell your house if the employer drops wages or worsens working conditions. In the case of trailer manufacturing, it becomes an easy way to skirt labor laws.
As far as metal fabrication goes, trailers for the light truck market are about the darkest corner there is. Most buyers are looking at price far more than quality, and the manufacturers give them exactly that. I have no doubt in my mind that Brian can design a better trailer, because most have little to no engineering or even thought applied to actually using them, they are designed to keep cost down. The materials, paint, wiring, and mechanicals are usually a abysmal at best, to the point at work we actually hire a company to come mess with them when we have problems. The genius actually said the wiring on a trailer was made for a Chevy, and that was why it wouldn't work with the dodge we were using
When you read that something's made with 12" 3/16 channel, what they mean in the trailer world is that they took sheet and stamped it to form a c shape. Actual c channel has extra material in the corner, which makes it dramatically stronger than the simple bent plate. Same with angle, etc. Using manufacturing methods like this is how they can build stuff so cheaply. Next time you get a chance, make a quick and dirty material list, and then call a steel supply house to get pricing. You will often find that if you used actual structural materials, it would cost a very large portion of the trailer cost, where in manufacturing steel objects labor is the major cost. By using lower grade materials, they are sacrificing longevity to meet a price point. Examine the other systems of the trailer, like the scissor mechanism (likely won't have bushings), the hydraulic lines (cheapest they could get), etc.
I've seen several brands, and I've been impressed by very few. We have a couple felling brand 17000 pound tilt trailers, and they seem about the best I've seen in a bit. When a manufacturer is pushed that hard to bang out product, quality suffers. The guys are on forced overtime, and throughput is pushed very hard from above. When a manufacturer is pushing for the lowest cost during this time, corners are cut because ot is higher than they calculated for when they priced stuff, and to make it work they actually have to produce more than they clocked stuff at. Turnover is shocking in a place like that, so despite the increased workload they are constantly training new guys, possibly on new fixtures, etc. What happens is garbage is sold as top shelf.
I've worked in the production manufacturing world, and I've seen this stuff first hand. While building your own trailer will definitely be the best you can buy because you can control everything, i understand that this is not practical for everyone. Brian, you bought a trailer after shopping around, had tons of problems with it, but have slowly gotten it squared away. You aren't happy with it and i completely understand that. If you come across a trailer that is built to your standards, then by all means buy it. But i would suggest either step up dramatically in quality (and unfortunately price), and/or have one custom built to your specs by a skilled small shop. That way when it's all said and done, you have exactly what you want, and will eventually forget the price when it becomes cheaper on the long run because it will last. You have one now, so you can run that till it's built.
I've slowly come to the conclusion that there are two kinds of people in this world when it comes to buying stuff. The first kind will buy a lesser product at a lesser price, accept that it sucks, and run it until they replace it over and over. The second kind is interested in value, and hates messing with crap that is always fighting him, so he buys the top of the line, and does it once. When i was younger, i was the first guy because that's all i could afford (i thought). Now I'm starting to see that if i buy quality stuff, my workday becomes much more enjoyable, and over time the product is actually cheaper because i don't have to replace it over and over. Obviously we're talking about stuff that we use to make a living with, not a tool we are gonna use once and then put it in the garage for 3 years till we think of using it again...
