We will be upgrading to a 8.5 by 20 trailer soon, living with a 7 by 16 is getting old in a hurry. What are thoughts on steel versus aluminum trailers, aluminum is going to be roughly twice the cost. Nobody can really give you a straight answer on weight savings but that is important for towing with our RV. The other point is holding their value, it seems like aluminum puts things in a different category with retaining value compared to steel.
Also, we live in Alabama and there are a billion trailer manufacturers nearby in Georgia. Its hard to tell how many of these trailers end up all over the country being sold under all different brand names, but it seems like there are lots of commentary on you get what you pay for. We keep trailers in our shop so I dont have concerns about rust.
