I hate to keep remembering this cause it makes me cringe...back in 2010, I had a salvage yard near me that had at least 100 square body trucks of all kinds on their lot. They had been there for years...I had no reason to believe they were going anywhere...but before I could turn around, he had crushed all of them...that steel went to China
I've lamented the exact same scenario here before--the one salvage yard nearby I go to most often had well over 100 of them too,and they were noted for "never scrapping much very often"...but when "Cash for Clunkers" came about,they had to make room for thousands more new arrivals,and steel prices were topping $250 a ton,so all the older heavier vehicles were the first to be squashed..now they have maybe 4 or 5 shells of cannibalized square bodies and a few Suburbans..
...hardy any in all the other yards in this area too now..
POS 305 and parts.
