How many army trucks at the moment have air springs? General vehicle installs are better now because the compressors duty cycle has been correctly engineered after the fact? Why have something that could leak in the first place if you want reliability first, comfort second?
Why is complicated better?
Why is complicated better? Because comfort and versatility matters.
In the military, only performance matters. You don't have your wife/girlfriend next to you for 18 hours. You aren't worried about how nice it feels to blast down a dirt road - only thing that matters is performance and longevity. You don't care about being able to ride at off road or street heights.
I live in the real world. Sound deadening, ride quality, and vibration/harshness is a thing and its an important thing. I have a 2 hour drive from Seattle to get to any of the fun areas to camp/wheel/etc. We own two Subarus yet drive the Rover every time despite it's fuel-hungry nature because it's nice to be comfortable.
I've owned Jeeps, I've owned Japanese trucks, Japanese luxury cars, Japanese motorcycles and European motorcycles. I love them all and for different reasons, but for extended trips,
yes, I prefer the higher complexity system that requires a little more PM/care/attention but delivers vastly higher performance.
I used to ride Japanese motorbikes. I rode my buddy's Ducati for a week despite being turned off due to the maintenance requirements and cost. After a week, I got back on my Suzuki and literally said the words 'What the F is this garbage" and immediately bought a KTM. Years later I tried to go back to a Suzuki, sold it after 200 miles, and now I'm on a Ducati which I put 6k miles on in 4 months.
If I was in the Congo, yes, I'd have a Land Cruiser. Or WR250R. But I'm in America. I'll take the Land Rover, Ducati... and someday the Porsche.
