>>1927027GMT400s are invincible as long as you keep the rust off the important bits and replace the fuel pump every 200k miles or so.
Mine is on 286k miles, stock engine, transmission, and fuel pump. Starts perfectly from cold even when it was -40 in the Midwest last year. Parts are also cheap as fuck and available everywhere in North America.
Pic related, bought it for $1500 in 2009 and it hasn't left me stranded once. Only work I've needed was new ball joints and an AC recharge. Got into an accident in her too, obliterated the other person's car, bent the bumper back with a chain and popped the headlight back in and drove it home. I trust these trucks with my life. Get a Burb if you want to sleep in it ofc
