Guys this is why you work on your car trailer
I've had my flat open trailer for almost 40 years (and had bought it used!). Great trailer, tows easily, very stable, and can take it most anywhere. Always garage kept. Love this trailer!
I got my 24' enclosed trailer last year. What a totally different experience. Makes it much more enjoyable at the track having a place to just hang out, etc. Tools, misc, etc. BUT....it comes at a cost of towing fuel economy, big to store it, and the worst is simply I can't just take it anywhere. Have to plan ahead for fuel stops as well as where I will take it as you can get "stuck" in places you wouldn't hesitate to take the open trailer. It has 6000# Dexter axles as those come with the bigger wheel bearings and brakes compared to the 3500/5200# axles. Has 8-bolt rims and bigger/higher load rating tires too.
Having said that, the boss (wife) really likes the enclosed trailer so that's what we use!! And after all these years, I may well sell my open trailer later this year.
