Oh Jeezus Keerist, Wabash and many others have been pounding 48,000# aluminum step decks and drop decks down the Interstate right alongside you for thirty years. Over half of the livestock in the country is hauled in aluminum trailers, which are routinely running overloads because the weight cops give them a lot of latitude on gvw's. Tort lawyers and insurance companies would have put a stop to aluminum heavy hauling if it was an issue.
I agree.
As for any new steel trailer... Look at the construction very carefully.
Most old trailers were heavy "C" channel... very clear on what you were getting there. Real steel.
BUT the past couple of years many manufactures have gone to box steel (think cheap ass metal building 14 or 12 gauge tube). No Thanks.
