Ash, the Ford Raptor probably isn't too far off what I reckon your creating with size, tow capability and power???
Engine types available in a V8 are 5.0L V8 and 6.2L V8. Engine Control System Electronic on both engines. Horsepower is (SAE net@rpm) on the 5.0 is 360 @ 5500 and 411 @ 5500 on the 6.2. Torque (lb.-ft. @rpm) 380 @ 4250 on the 5.0 and 434 @ 4500 on the 6.2. Recommended fuel Unleaded regular on both with fuel economy suggested at 5.0l = 15 city/21 hwy/17 combined mpg (4x2) and 14 city/19 hwy/16 combined mpg (4x4). The 6.2 gets 13 city/18 hwy/ 14 combined mpg (4x2) and 12 city/16 hwy/ 13 combined mpg (4x4, 2011 EPA-estimated). all stats taken form the Ford F150 website. Not sure the quick way of doing a MPG - L/100 comparison??
Great to watch your progress Ash. Making room for the baby seat/s I hope?
