Car Haul Trailer, Steel vs Aluminum, Which Would You Choose?

I have had both, just sold a Aluma trailer full deck 18' all aluminum trailer. It comes down to two things how much you want spend and how much you are going to use it. If you are going to use it a lot and tow all over the place , then go with aluminum. if you are going to use once in while go steel.
