Now, I'm going to make a rather broad statement here based on mostly anecdotal evidence. The guy who replaced my boat trailer springs told me not to expect to get more than three years out of the new pair in a salt water environment as they were Chinese steel, and if I opted for American steel, he could get springs from another source and they would last much longer but at much greater cost, and with a shipping delay.
He went on to say we ship our steel scrap to the Chinese and they returned to us steel products that are not mfgrd. to American standards. I've researched this a bit and I suspect he told the truth. So, does anyone here think RV mfgrs. are using Chinese or American steel on our RVs?
