My thoughts as well, Maybe they were lifts or something

Struts and shocks can last maybe 50-100k. If you’re beating the crap out of your truck you might be on the low end of that scale. Maybe that’s what they mean?

20 years on the hard 4wd trails of AZ, CA, CO, NM and both MX BCN and Sonora. A couple of hundred miles on the Baja 1000 route with a bed full of camping gear did one suspension in. And there's a lift/helper leaf in there.

Never once left us stranded.

Ah I see. Ok, that makes sense then.
