My parents bought a Sears Cold Spot deep freeze around 1963. It ran constantly and problem-free until last year, when my father shut it down because he no longer had a use for it.
It's still running. Only downside to it is that it isn't frost free. Has to be defrosted periodically. And I'm sure the enviro-whackos would be displeased. It's an energy guzzler. But it keeps everything frozen.
Today you can't buy a freezer that big. And with all that digital and energy saving carp, new freezers (and appliances in general) don't last more than 5 years. For all the money we spend on these appliances, we get garbage.
3 years ago I was living with a friend on his great aunts farm. AujtbAida had bought a similar vintage Cold Spot chest freezer and I think I was the first person to defrost it since his aunt died in the late 1990s. It was a bit of an energy hog as it sat in an unventilated lean-to off the house and that lean-to had a huge solar load in the summer.
