When I was shopping for trailers, I looked at Gatormade, among others, and the ones I looked at appeared were nice and offered excellent "bang for the buck" considering the prices they were asking for them. With that out of the way, I tend to lump Gatormade into the middle rung of new trailers. Lower rung new trailers tend not to be painted underneath and come with used tires. At the middle level, trailers are a lot like budget level trailers, but with new tires and maybe some paint underneath. At the top end, trailers are built heavier, nicely painted top and bottom, come with new (and often better quality) tires, and a price roughly 50% more than mid-range trailers. The key to being satisfied with the deal is going into it knowing what to expect and knowing what you're getting for your dollars.
My personal trailer is a Hurst--I'd put it about on par with a Gatormade, maybe not quite up to the ones I looked at. It's painted top and bottom and came with new tires. It's great at the price I paid, but hardly the best. I'm not disappointed because I knew what I was getting--it wasn't a $3500 trailer, but it didn't cost that much either. I consider Hudson Bros. trailers to be top tier (maybe not as pretty as some, but all I've been around have been really well built), and that's what I would've bought if I'd been buying for business or if money weren't a motivating factor.
All of this is to say, if you have a defective trailer, you shouldn't have to accept it, but if there's a problem you can easily correct yourself, you'll probably be money and frustration ahead to do it and chalk it up to experience. Good luck and I hope you get an outcome you can live with.
