They do. No idea what craigy thinks is an extended mileage tank.
Silverbolt and ovrlnd appeared to be suggesting/agreeing that because the 36 gallon extended tank was not listed as an option on the leaked order pics, that it might not be offered, and that the dual exhaust was possibly to blame.
I personally think that it would be ridiculous to scrap the 36gal tank for the sake of a dual exhaust.
Now for ground clearance, less weight, I can see the argument, but it would still be unfortunate.
The 36 gallon tank is advertised and listed by Ford as an "extended range fuel tank" in the brochure/options list for the F-150. Personally I'd love to see an even larger tank or a dual tank factory option. I am personally not a big fan of carrying cans although I do sometimes.
My bet is that 36gallon is going to be standard equipment on the Raptor (not optional), but we will find out soon enough.
