If you plan on driving the wheels off it, I’m guessing you are talking 150k-200k+ miles. At a $50k F150 compared to a $80k F150e you will make up that $30k in fuel (at current prices) and PM in ~60k miles. At 200k miles operating cost of a ICE $50k f150 you could probably buy two F150e’s.
I’ve gotten to the point where I’m at $12 in fuel to drive my LX570 round trip to Costco. In my Tesla is it $0 (I have solar) even if I paid rack rate for the electricity it would be $0.10. Also have to consider PM. EVs have no oil changes, no transmission, no transfer cases, a very simple cooling system. 8 years in teslas and my PM has consisted of 4 bottles of brake fluid, I do a flush every 2 years. Same time in my LX looking at my log book (do my own work). 16 oil changes, 4 brake flushes, 4 f/r diff fluid changed, 4 transfer case fluid changes, 2 AT fluid exchange, 1 coolant exchange, 2 ACH fluid exchanges. Ballpark this was ~$3k just in fluids/filters/crush washers. Would have been $10-15k if I had it all done at the dealer, here in Alaska closer to $15k.
