I view the CP4 issues like the Porsche IMS bearing issue. Rare but sucks bad if it happens to you. Probably a bit overhyped because of the internet. Definitely going to lose my CP4 now that I typed that out but there are a LOT of CP4's out there with big miles on them in commercial use.
The last two tow rigs were an LBZ that went down twice and a 7.3 that did its best to strand me a couple times too. Shit happens even on old non-emissions trucks. Once I get stranded twice by a tow rig, it's gone. Can't afford to have issues on the road going to a race. LBZ was bought in 2009 with 65k on it and sold in 2019 with 250k on it, 7.3 was bought in 2014 with 99k and sold in 2021 with 200k on it. Current truck is a F350 dually that I bought in 2021 with 60k on it and now at 98k. I've had really good luck on a cost per mile basis buying around that age and running to roughly 200k so I plan to do the same on the 6.7.
I hear ya, as they say, “if it has tits or tires, your gonna have problems”
Even if it’s rare, there’s a reason ram stepped away from the cp4. There are other units out there that have lower failure rates.
I think half the problems with these older diesel trucks is that they have been fucked with by 4-7 owners now. They are usually fucked with by people not knowing what they are doing because it’s some teen who got his first diesel, or some guy who can’t afford a new diesel and is doing ghetto shit to keep the old diesel running because no diesel is cheap and most of the older diesels have 200-400k on them now which allows for random failure.
The idea of a new diesel, is that you don’t have these problems and unfortunately I think we, the people, have become test dummies for these manufacturers as they don’t throughly test this stuff out like they used to, as the bar is always changing for epa crap and they are jumping through hurdles on emissions standards.
I’m not trying to sell anyone on the older diesel life. There’s downsides. They are loud, slower, require more maintenance, etc.
I am genuinely intrigued to see where this goes. There’s 1000 ways to skin a cat and I thoroughly enjoy seeing how we all haul our crap to the desert, or forest or wherever we are going to use our rigs.
I’ve seen big diesel pusher RVs leave people stranded, and I’ve seen success with them.
I’ve seen the class 8 semi setup work well and not work well. Like the time Erik Miller had a motor go out halfway across America on his way to KOH.
Old diesels work well, and fail.
New diesels work well and fail.
You get the point, it all works until it doesn’t and unfortunately, I’ve seen high dollar setups fail and low buck setups fail.
One thing I do wish I had was the dedication to your 2 time stranded rule, I don’t think I’d have my rock crawler or truck anymore if that was the case lol
