those who can afford to spend 60k for a new rig,are not the type to care if the engines easy to work on or not,as they wont be doing any wrenching.
they buy the 200k+ mile warranties,and sell the truck before it expires and do it all over again.the ones who will keep their 60k dollar rigs past warranty will pay to have things fixed.
very few with this kind of $ even care whats under the hood,as long as they know when they hook onto a heavy trailer or 5th wheel,they can go 80 lol.
new trucks are not made for the home shade tree mechanics.we can't afford them lol.
look at them KR's they are made with leather seats and setup like fine luxury cars.
those aren't made for working,and will be sold to people who don't need them just city slickers who simply want them to make themselfs think they work trucks like we do thats all.
even if they where easy to work on.people who can pay 60k for a pickup wont be doing anything to it themselfs anyway.
they see a truck with 390 hp and 735 lb-ft with leather seats.they dont plan on popping the hood to get dirty.
