Having owned a Dodge 4wd (1977?) with the Mitsu “forklift” diesel I chuckle.

My employees hated that pickup because it barely crawled up our steep gravel road hills.
They beat up and mistreated it hoping to kill it.
I gave in and auctioned it off, brought $1100.

Thing is, I continued to see that black Dodge diesel running on local roads for at least 15 more years.

To replace it I bought from Memphis Equipment a refurbished US Army 4x4 pickup.
Super stiff arched leaf spring packs.
Would jar the fillings out of your teeth.
Employees complained about that too.

One day I noticed that 3 leafs had disappeared at each corner.....
