Aluminum trailers are rediculously overpriced for the little bit of weight saving. Remember, aluminum has to be twice as thick as steel to be close to as strong. Go buy one of those cheap, steeel mesh floor jobbies with 12" tires. After the first set of tires burns up (under a year) go have some 12" radials mounted up at your local used tire store. Also, mount up a cheap wheel chock. Done. If you are patient, you can find these trailers used for a few hundo.
