That's a sharp truck. When I found mine I had a short list of must-haves, one was nav (and so decent backup camera, those rearview mirror ones are ridiculous) and the other was 6.2L (no firsthand experience against the 5.4L but the spark plug horror stories were enough for me). I'd rather have a SCAB but they are/were scarce and the SCREW gives you so much more space, and the 36gal tank.
Anyway to the actual question about maintenance cost, I rate it super cheap...until you come here lol! If you can resist the temptation to upgrade, it's next to nothing. Especially if you do your own maintenance, with the caveat that if you hammer the dogshit out of it, things will break/wear faster. I'm at 195k now, I'm averaging 5-6k miles a year working at home so this year maintenance cost me $47 for the Motorcraft filter and Mobile 1 oil at Walmart. Next year I want tires (I could milk them another couple years at this rate, but want em) so $1500-$2000 and that'll last me 5-ish years. At 200k I'll change fluids (transfer case, diffs, transmission-all done at 150k when I bought it), at 250k spark plugs (there's 16 of those little bastards) along with coolant, radiator hoses, brake fluid and serpentine belt (as preventative). Shocks yes good idea to buy new and have the originals rebuilt, if you're really industrious you can rebuild 'em yourself, but still, aside from tires (well and gas heh) that's your biggest expense, again depending on your use case. Hope that helps, good luck!
