I would skip the 1 or 3/4 ton and go for a Raptor. The road I'm travelling is 110km of pure washed out shit and it's already shaking my 1 ton loose at only 50000km.
My cross shift has a Raptor with 100000km that still drives like new, I've borrowed it a few times to go to the gym and it's night and day compared to my truck, it feels like it's just gliding over all the wash. Another guy I worked with had over 200000 on his and it ran like a top with no issues, told me it's never once let him down and he's still driving it so he must be at at least 240-250k km.
We stopped checking for monsters under our beds when we realized they were inside us.
