Oil change on my 6.7 is less than $100. I do it myself, I could list several horror stories about somebody else changing my oil. The engine oil is not the problem.. the fuel system is expensive even doing it yourself and without the right process after changing it’s easy to get air in that system... and that you do not want Just cycling the pump turning key on for 30 seconds, 6 times, pressures up fuel system after changing fuel filter. It’s in the owners manual.

God Bless Cummins! 2,755 miles pulling a SxS on an 18 foot trailer from DFW to Moab, Ut to Sedona, Az and back to DFW. That horrible 68RFE turning 35’s sure did a good job, never got above 165 degrees and easily maintained 80-90 mph through the mountains and got an overall average of 14.6mpg. Stupid Ram, you’re not supposed to still be running

I know right!?!? If anything it’s a parachute. I get better fuel economy pulling a 30 foot camper. It’s amazing how much drag a SxS has. The new one has less drag than the old one, it weighed less but would suck the fuel mileage down to around 11.5-12.5. Weight isn’t everything

I can get a 5 gallon bucket under my F250 and added a Fumoto valve. Oil filter right there as well. Super easy and I do it myself. Wife and daughters cars I have done....too hard to crawl under.
As for the pool, I'd rather manscape with a weed whacker than mess with the pool. That gets outsourced to the man.

My point is it’s still less than half the amount to service the gas

There must be a huge margin on what parts/service actually cost and what we pay for them.
ON my RAM a fuel system replacement, HPFP, injectors, lines, in tank pump and flushing the tank runs $12,000-$15,000. A turbo is $4,000+ You can buy a new crate engine from ram includes everything including a new turbo and HPFP for $7500 and have it installed for $2000.
I only paid 35,000 for my truck new, the parts cost added up is 3x what i paid for the truck including profit.

BP has a nice truck - the Cummins motor is, by far, the most reliable of the big 3. I say that as the owner of a Duramax. But the drive-ability of the Cummins is not great (poor turning radius, rough suspension), and they do have problems with the 68RFE if you tow anything heavy, run big tires, etc. My Allison is probably the most durable of the big 3 transmissions, especially if you keep the Dmax at stock power levels.
As for gas vs diesel cost, it's a toss up. Diesel will get better mpg, but cost more up front, more to maintain, and more to repair. It's just not reasonable to put a huge gas engine inside a truck that weighs 9000 lbs and then ask it to get good fuel economy. But for the OP's uses, either will do. I do change my own oil in my Dmax - it's like $40 in parts and a half hour in time...so I really enjoy it personally. Everything is easy to get to and I know it's done right.
Personally if I was the OP, I'd look hard at a Ram half ton with the Hemi. Assembled in US and they're a really comfortable truck that can pull and get good mpg. But I know the half ton idea isn't that appealing...so do what you wish...

I only paid 35,000 for my truck new, the parts cost added up is 3x what i paid for the truck including profit. This must have been at the dealer using OE parts. Aftermarket injectors run $1800-3600, cp3(hpfp) run $1100-2000, LPFP $350, new aftermarket VGT with exhaust brake is $2300, non vgt with no brake is $1300 and all can be done under the hood. Add two more injectors for a duramax/ford, duramax and cummins both use a cp3, for hpfp is about $1500 higher and you HAVE to replace all the lines since the guts are aluminum and cant get flushed out. All new trucks use a VGT turbo with integrated exhaust brake and can be converted to a non vgt. Most of the turbo/fuel related cost come into play with GM and Ford requiring the cab to come off. With and I6 it can all be done under the hood.

Mine is in regaurds to the 1/2 ton ram and you have to yank the cab to do most of it as well.

You either have the largest tank they make or you drive slow. That’s incredible mileage. My 31 gallon tank gets me roughly 450 miles on 3/4 tank, which is roughly 19mpg.

But I know the half ton idea isn't that appealing...so do what you wish... back pre-DEF and emissions a Dodge Cummins with a tune would get great mileage. My partner had a 2011 Mega Cab that was chipped and tuned and had an ungodly amount of power ( i think 1100-1200 ft.lbs of torque estimated ) that would get 22-24 mpg on the highway. I knew quite a few guys who would get 22 mpg in a Cummins with mild tunes. I agree with your assessment about transmissions. If they would put a Allison Transmission, a Cummins inline 6 inside a Ford frame and body it would be the ultimate truck. My pause on cummins was never the engine, it was the trucks they put them in. I remember the owners of duramax's also gettting pretty good 20+ mpg ranges pre DEF. None of them cared for pulling with the D-Max's though. I hear that has changed and the Chevy is now a contender as far as pulling power goes.

We have had a few empty highway runs in my dads 2018 cummins 3500 srw crew cab long bed 4x4 with the aisin trans. Cruise set at 65 mph for a 100% hwy tank it has done as good as 24 mpg hand calculated. That is stock all emissons intact with just shy of 400 hp and close to 1000 foot pounds of torque.
