2011 Ford F-150 SuperCrew XLT 4dr SuperCrew 4WD Styleside 5.5 ft. SB (5.0L 8cyl 6A)
The F150 Super Crew with 3.5 eco boost engine (Edmunds doesn't have this selection on their pull down menu) has been very reliable and has plenty of trailer pulling power. Actually fuel mileage with regular fuel (up to 10% ethanol) has been 16 city and 19 highway, if you can find non-ethanol fuel you'll see 19 city and up to 24 highway a substantial difference. I have 46,000 miles on my truck and have just replaced the battery. You can't beat the rear cab for it's roominess, and ease for getting in and out of, Ford should had put a grab handle on the drivers side. I strongly recommend have a spray in bed liner done to help preserve the truck bed.
The only issues that I have encountered:
1- I did have power issues during a rain storm on several occasions, Ford did a mod on the intercooler to correct the problem. 2. The airbag light kept coming on, Ford replaced the drivers door cable which had issues, this took 4 trips to the dealer to resolve. 3. Rear window/mirror defogger failed, Ford replaced the rear window to resolve the problem.
I strongly suspect that Ford (not just Ford) uses non-ethanol fuel when they come up with their fuel mileage figures, because I have never owned a vehicle that got their stated mileage unless I run non-ethanol fuel which as most of you know cost from $.50 to $1.50 per gallon more to purchase if you can find it.
