2012 Ford F-150 XLT

The 2012 F-150 is part of Ford’s 12th generation of the F-Series (introduced 2009-2014 body style). The 4×4 Crew Cab (“SuperCrew” in some markets) is the four-door version, offering full rear seating and ideal for hauling people AND stuff. It’s built for work, towing, off-road, and family use.
Engine & Performance
Various engine options in 2012, especially for 4×4 CrewCabs:
3.5 L EcoBoost V6 — twin-turbo, direct injection. ~ 365 hp and 420 lb-ft torque.

Transmission is a 6-speed automatic. The 4×4 system gives added traction, useful off-road, in snow, mud etc. MotorTrend+1
Fuel Economy
With 4×4 and the EcoBoost engine: ~ 15 mpg city / 21 mpg highway.

Other engine / drivetrain combos (V8s, V6 without turbo) vary; usually less efficient. DealerProcess+2Edmunds+2
Size, Dimensions & Capacity
Wheelbase for Crew Cab (5.5 ft or 6.5 ft bed options) is around 144.5 in for many 4×4 CrewCab setups.
Overall length about 231.9 in for the shorter bed version. Width ~79-80 in, height ~75-77 in depending on trim.

Seating for up to 5 or 6, depending on front seat layout (bench or buckets + center console). Rear seats are reasonably roomy. Kbb.com+1
Towing & Payload
Max towing capacity (when properly equipped) can be up to 11,300 lbs.

Payload capacity depends heavily on configuration (bed length, engine, trim, optional equipment). Typically in the range of ~ 1,500-1,800 lbs for many CrewCab 4×4 setups. For instance, a Lariat 4×4 model shows ~1,520 lb payload.

Features & Trim Options
Depending on the trim (XL, XLT, Lariat, King Ranch, etc.), you can get options such as:
Chrome appearance packages, upgraded wheels, nicer upholstery, interior tech (infotainment, navigation) etc.

Off-road packages (e.g. FX4) that include skid plates, upgraded shocks, etc.
Higher trims add comfort and convenience features like heated seats, upgraded audio, possibly trailer tow mirrors, etc.
Strengths & Good Use-Cases
Strong towing / hauling ability with good balance of power (especially with EcoBoost) and capability.
Comfortable for passengers, especially rear-seat, because of Crew Cab’s four full doors and decent rear legroom.
4×4 gives greater capability in rough terrain, winter driving, off-road, etc.
Many trims/options make it flexible: can be a work truck or more luxurious family hauler.
Common Weaknesses / Things to Watch
Fuel economy drops with 4×4, especially with V8s or when towing.
Complexity of EcoBoost (turbochargers, direct injection) means potential maintenance costs; e.g. ensure turbos, cooling system are in good shape.
Heavier drivetrain adds weight; can affect ride, handling, maintenance.
Depending on bed length (short bed 5.5 ft vs longer 6.5 ft), usable cargo bed space varies.
Older trucks may have rust issues (especially frame), wear in suspension, or transmission/transfer case issues depending on upkeep.
If you tell me the trim level (or what you care about: towing, comfort, fuel savings), I can give “your particular model” specs — what it's like to own one. Do you want that?
