It's a no brainer that new trucks under warranty where you just squirt some grease in them & maybe put a tire or 2 on them once in a while is way more efficient than an old truck that you're spending every Saturday and sometimes a night or 2 during the week working on. My log truck payments are 4000 bucks a piece and and they get washed fueled greased and go. When they hit 5 years old I will trade them in. All of this crap about new trucks breaking down all the time is an old wivestale. If that is the case those guys were probably still washing their clothes on a buckboard.
I don't know about you guys but there's no way you can have an old truck that you're making a $1000 month payment on and have it come out cheaper to operate per month than a brand new one where the payment is $4000.
Just in from the hot sun wrenching on my service truck, lawn mower, and tractor and taking a break.............i gotta chime in on this. The benefit of working on your own truck is that you can see what needs to be done, the condition of crap on the truck, and you take the extra effort to do the extra stuff that others might not do.........never seize the fasteners instead of putting them on dry, see a potential chafe point and put some chafe guard on BEFORE it happens, fluid film that developing rust spot, throw some grease here, etc.
I am a self employed heavy equipment mechanic, like Mike; and have a few customers who do site development. One good customer has a bunch of CAT equipment and Mack GRU dump trucks. This past winter........could be fall..........one of the drivers complained about long crank when the engine was hot. MP8 engine.............2018 truck...........about 130,000 miles at the time............needed injector cups. So this was in Febuary. Told the owner we could do it over a weekend at his shop (when I say 'we' I include him and myself......he's a hard worker and gets right into it and helps........I respect the hell of him and his work ethic) or he could send it to Mack. He looked at me and asked if I had ever done those before...........I said "No...........alot things I haven't done before. There is always a first time but I'm fairly confident we can get it done without a problem..........that's why I said over a weekend.......just in case we run into a problem." He said........"Yeah, what if you need other parts?? Then what??" I answered "Well, we'll just have to wait and get the parts then." He said "Don't you have bigger fish to fry?? (as in working on his loaders or excavators)"
The short of this is..........he decided to send it to Mack. I called, made an appointment, Mack was booking over a month out, verified they had a cup and injector kit in stock.......(they had 3 in stock). The appointment was late in Febuary during school vacation week when my family and I go skiing. So Monday morning first of school vacation, the truck goes to Mack for a 1 day injector cup replacement. The following week I come home from skiing and get this text..........'How was skiing?? Are you still up there??' ............not good..........I replied ' Skiing good..........I'm home'............phone rings 2 seconds later.
The truck is still in the shop, they took the injectors and cups out BEFORE verifying they had the REPLACEMENT PARTS. Now I get involved with the BS going on with the dealer. Dealer can't source the injectors (crazy right??!!) Call parts..........one parts guy is saying he can get injectors overnighted for tomorrow...........I order 6 injectors. The following morning, no injectors. Another parts guy says the first parts guy is full of **** (direct quote) and there are no injectors to be had. I call back later and talk to first parts guy I talked to and he says the injectors are coming and the 2nd parts guy is full of ****!! Again, direct quotes without me saying one parts guy is saying the other parts guy is full of ****.............UNREAL!! The short end of it...........I sourced injectors from another shop in the southern part of the state, had them shipped to me overnight, then hand delivered them to the dealer. That was on a Friday morning...........the truck has NOW BEEN DOWN 2 WEEKS. Didn't get put back together until the following Monday..........picked up on Tuesday.
I've ended up getting involved with resolving dealer problems quite a few times with regards to customers.........and the company my wife works for.........all because the dealer is playing games and screwing things up.
So the last thing I really want to do is work on my own truck or work on my wifes Expedition.............but.........it needs to get done. I'd rather do it than see it come back with questionable work or have someone else screw the pooch fixing my truck. I'd rather know what short cuts I'm taking and deal with them later than find out later SUPRISE!! They screwed this up!! Or didn't do this when it was staring them in the face.
I write off my time and the parts I put into my equipment. Nope, doesn't make me money but it gives me piece of mind. Seen too many WTF fixes.
