I did a ton of shopping and comparison and settled on a PJ. Mine is a 38 ft. Have had it for 6 years. Have never had an issue and use it hard. Thats all I got.
Whatever you can find cheap on Facebook marketplace with heavy axels. I don't even know what brand mine is, but I bought it off the side of the road for $2500.
A lot of the hotshot companies we deal with swear by Load Trail. I've got a BigTex that I've had for about 20 years that is built like a brick **** house. Never had a problem with it. Look at a few and you can tell which ones are built heavy and which ones aren't.
If you are going with a major manufacturer, the only thing that matters is the specs on the trailer. Can it handle the weight? If so, get the one that fits your budget. I always go used market for these. Same quality, but let someone else take the hit. These are all steel and welds, the designs may be slightly different and the stickers on the side are different, but it really makes no difference.
