No recommendations, just some random thoughts. I've been looking at trailers for a while, I've got two goosenecks and two little trailers, one a pintel and the other a standard bumper pull. Would like to get down to two that'll do everything it now takes four to accomplish.
Check out electric over hydraulic disk brakes, some are offering this as an option.
If you ever haul hay of lumber and need to use the full length of the trailer you might ask about a fold over plate to extend the trailer floor over the fold up ramps.
Also, springs to help raise the ramps are nice.
The Big Tex factory is only a 3 hour or so drive for me. They're in Mt. Pleasant, Tx. My brother and I drove down and picked up his trailer last year, he saved by buying direct, and they had a model that was slightly damaged by a unskilled guy in there storage yard and he got a futher ($500) discount. If you have the option of buying direct from any manufacture, you might want to check that possibility out.
Also, dealers will sometimes carry new trailers to equiptment auctions this time of year and sell em at a good price, they would much rather sell it at near cost, than pull it back to the dealership.
About buying at an auction, you really need to do your homework so you don't pay too much.
Good luck, Ronnie
