The pricy failures with diesel engines that friends have had were turbocharger failure and two trucks with injector pump failure, two different trucks. Possibly just crap luck? If I remember correctly I could get another gas engine for less then the injector pump.

Lets start with 15 qts of oil every 5000 mi. Fuel filters every other oil change. Dual batteries. Plug it in below freezing. Etc. And yeah, the life cycle is longer, but only if you're keeping the same truck for 250k, or buying really used. Transmissions often get eaten up by then too.

Yes, the Jake is nice, Fords don't do that but do have a downshift on braking feature that's similar.

If you really want to stabilize towing, ditch your bumper hitch trailer and get a gooseneck. Worlds of difference in stability.

Extra cost per mile imho. The easy one is common rail’s requirement for clean fuel. Using high end 2 micron fuel filters that must be replaced frequently, plus the dreaded bad batch of diesel or the station/end user filling with bio leads to $3500 worth of fuel injectors(see below). Then the whole thing about every new truck using cp4’s that will grenade, which Cummins switched back to cp3’s on the gen 5.

AND

Gelling diesel is another fun one.
3 gallon oil changes using full synthetic is costly.
Bruce jenners just don’t last as long.
Emission equipment that makes idling the truck and short trips a killer.

But boy oh boy is that torque intoxicating !

OP-

I recently purchased a lightly used 2024 Titan XD Pro-4X. It's a longer wheelbase...heavier frame, rear-end, springs, etc (about 700 pounds worth). To date, I'm very impressed, but it's just under 30 days in. Plans for towing the race-car hauler, and a 26-28 foot center-console.

With the Titan being discontinued, prices were all over the map, but I saved a quick $20k over the GMCs w/6.2 I had been shopping. And I don't have to worry about 6.2 recalls/block ventilations. The 5.6 Nissan is good for a solid 400hp, and doesn't have start/stop, cylinder deactivation, or fragile lifters to worry about.....what's not to love. The second buyer also gets the full coverage of the 5 year-100k warranty.

Your original post did not mention it, but if you haven't been using a weight-distributing hitch....get one. It will greatly reduce any angst from towing a 28 footer.

The 6.7 Fords are very expensive. Seems like any sort of engine work requires one to pull the cab. 8 injectors are going to be more expensive compared to Cummins’s 6.

Cp3’s on the Cummins are around 1100 for a new Bosch unit.

Not bad luck. Bad fuel and dirty filters.

I change the oil in my Duramax every 3-4k with synthetic oil . I change the air filter every two years . I drain the transmission fluid every 50k and install a new spin on filter . That's been my routine for years . Not much more than a gasser .

As long as you do not plan on towing over any serious mountain passes gas is fine.

Out here in CO the altitude makes a huge difference.

All Fords since the 6.0 are cab off for any major engine work. The big shops are used to it, kinda like the audi guys are used to taking the front of the car apart. But it does add a few hours.
But yeah, the fueling system on any diesel is going to be more problematic and $$$ compared to a gas truck.
My take is diesel is great if you need it or buy it used but cared for (and, cough, deleted, cough).

My old 7.3 Power Stroke does require 4 gallons of oil for an oil change but it's more like every 7-8k miles and it's non-synthetic Rotella, or whatever brand is on sale. The filters were only about $10 when I bought them, (for some reason, I have a lifetime supply). So an oil change is around $80-100. Big deal. The amount I drive it, maybe once a year.

Same with fuel filters...I feel like I can never change truck platform, I have about a case of those. I'm like a squirrel who hides nuts for the winter and then forgets where he put them, I must always forget that I bought them already and bought more.

Tires are expensive but they last pretty well if you get good ones. The last set was around $800 and I'm sure they've gone up. PU trucks in general are an idiotic expenditure for most Americans who have them, (no one else buys them, maybe Canadians?), I barely justify mine because I occasionally use it to pull trailers, etc.

I'd love to have a new F-250 6.7 truck and a reason to need/justify it, (diesel only for me), but I don't. Not even close. My close friends just bought a new Tundra, beautiful truck with 4x4, loaded...they don't tow or haul anything but surfboards and a toddler. They bought it because they liked it and they could. That's what drives the truck and SUV market in America.

I'd love to buy a used vehicle from you but that oil change interval is overkill. If you sent a sample to Blackstone with 6-7k miles on it, they would probably tell you that it's clean and to extend your intervals.

I bought my first truck which was a used small 2wd '83 Nissan in '88 when I started racing MX and needed to haul my CR250 to the races. That lasted me about 10 years and I only used it when I needed to haul something for the most part. My wife then talked me into buying her a new Dodge Dakota 4x4 as she wanted us to have a 4x4 for when our rural roads drifted over. She drove it daily for a few years until the warranty expired and I refused to keep repairing that pos lemon. I then bought a used Tacoma 4x4 which lasted a long time until Toyota bought it back from us for big $$$ due to a frame rust recall. Next was a used '02 Tundra Limited which served us well and now we have an '11 Tundra Limited which only gets used on occasion when needing to haul or pull something. The '11 will likely last us many more years as it only gets used primarily for pulling the boat to the river or lake and an occasional Menards run for building supplies.

I hate daily driving trucks vs cars. Pain to get into some parking spots and they eat more fuel. That said... half of the parking lot at work is filled with newish expensive trucks that my coworkers rarely haul anything with. I don't get it.... They could have a couple nice used comfortable cars and an old roadworthy used occasional use truck for less than the price of the new fancy trucks they commute in.

I agree that the frequent oil change intervals are a bit much, but have you priced a high pressure oil pump lately?

When it comes to towing large/heavy trailers, you want MORE capacity than needed, not less. There is an inverse correlation between the weight of a trailer and its safety in a panic stop, etc.

Airstreams are light. I have two of them. Nothing against your RR but anything will tow an Airstream, they are made to be towed by cars. When my ‘63 Airstream trailer was built, absolutely no one used a truck to pull one.

Ah. Back when normal cars had real frames and big block engines.

I hear this all the time, especially from Airstream dealers. My 28’ trailer is a 2011 Airstream Flying Cloud and even though it’s GVWR is only 7300, the tongue weight is 976. My truck’s payload capacity is only 1488 so even with weight distribution set up I have, I’m still pretty close to maxing out payload because of my fat ass and cargo.

If I can’t find a 2500 in my price range, I’m going to sell my 27’ Flying Cloud and get an Airstream Basecamp 20X. I can pull that my the Titan or my wife’s big SUV.

If you're rollin like a "Carolina squat" with the tongue load, just add some airbags designed for lighter duty trucks. With my F250 I have 5000lb airbags under it. I can put a 3500lb mini skid steer all the way at the front of my trailer and not lower the back end of the truck. FWIW I ALWAYS pull tongue heavy. I'd rater squat the back than have the tail wag the dog on a downhill grade.
