Car hauler trailers

I’m going to be looking for a car trailer soon. I’m thinking I want an 18’ steel deck with the standard 3500lb axles. Aluminum trailers are cool but out of my budget right now. My parents have a 24’ enclosed car hauler that is now a storage shed, and is a little too big for my 5.7 1500.
What type of trailers and set ups do y’all have, recommend, or want? Brands to stay away from? Favorite upgrades?
Thanks
