Alright fill me in on why the maintenance is more money.
And don't give me some BS about the dealer charging youore to work on a diesel.
Walk into the parts store and buy a Wix oil filter for a SBC and a 5 qt jug of whatever oil is on sale, it all sucks about the same now anyhow, but none of my engines are flat tappets. Every 3 years you need a $10 fuel filter. Every 7 years you need a $150 secondary tuneup and replace the air filter and pcv too just cause (never let the air filter go long enough for the indicator to show anything). Every 3 weeks you fill the 40 gal tank with about 30-35 gal of 87 octane and hope for the best since there are no name brand gas stations left in your area.
Wife's Expedition goes to the dealer for oil changes when the sticker tells her to and she gets around to it, $25. If it goes 3 years in between repairs it will get fuel filter as maintenance, not part of a bigger repair. Both vehicles are running Michelin LTX M/S2 tires which last great and have excellent wet weather handling... they go about 6-7 years before they need replacing... Wagner brakes go about the same. I buy when they're around 10 years old and about 10% sticker price. @2 years in the heater core blew and the wife drove home... so expedition maintenance schedule included HER joining me in the junk yard to pull new/used 2v romeo 4.6l (somebody had to watch the tools and get a little dirty pulling the stuff out + good punishment factor for "I only drove home") that PM service cost close to a grand by the time it was all done, but also got new timing set and ign coils as well as regular stuff. Otherwise it would get a set of single platinum plugs every 70k.
I'm cheap... I look at maintenance part prices when I shop for a driver, and I don't put on enough miles for that stuff to get out of hand. I didn't want the expedition, but the pedals moved and I lost that battle... at least with the 4.6 2v it was cheaper and easier to deal with than a 3v or 5.4 when I had to replace it, which was part of the purchase decision. At 180k miles I didn't feel it was worth even looking inside when she popped the head. Junkyard wrecked Grand Marquis $350 engine solved my problems much easier than pulling from another truck or repairing what I had.
Diesel would cost more to buy Filters for than my "normal" PMs, neither of us pulls the weight to use the extra torque... but we both need the cargo space. Been running the suburban since 2008 and the expedition since 2012. My pickup is strictly short run beater duty and gets used leftovers from the suburban. My old 93 roadmaster was even cheaper than the suburban to keep on the road, I'm thinking about another.
If your pulling the weight, I would go diesel any day. If your burning the miles, there's a lot of ways to go for mileage... like a Honda.
