Francesca is right, of course, there are lots of aluminum-framed trailers... with extensive aluminum deck structures (such as the car carriers and that snowmobile trailer) or a whole aluminum body (such as the Camplite, but notably not the megadollar classic Airstream). If you're not joining other aluminum parts to it, and the metal is not a significant portion of the trailer, I see little point in making the frame out of aluminum at twice the expense of steel... but if you custom-build a nice one (as Karl's friend did), good work, and show us photos (as Karl did)!

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.
