The Ford F-150 has been the best-selling vehicle in the United States for over 40 consecutive years. In Lake County — with its mix of rural properties, construction trades, and suburban commuters — you'll find F-150s everywhere. That widespread availability is both the good news and the complication.
Two F-150s with identical years and mileage can be in entirely different condition depending on how they were used. A truck that hauled landscaping materials in Waukegan is a different vehicle than one driven to an office in Libertyville. Our RideCheckers have inspected dozens of F-150s across Lake County, and there are three areas where we focus first.
1. Towing and Payload History
The F-150's towing capacity ranges from around 5,000 lbs on a base V6 to 14,000 lbs on a properly configured Max Tow package. A truck used heavily at or near its tow rating will show it in the suspension, the hitch receiver, the transmission fluid condition, and sometimes the frame.
- Check the hitch receiver for wear, welding evidence, or aftermarket installation
- Inspect trailer brake controller wiring if present
- Check the rear leaf springs or air suspension for sag or uneven compression
- Pull transmission fluid — dark or burnt fluid is a major indicator
- Look for frame flex stress marks near rear spring hangers
Field Intelligence
A truck with a tow package on the window sticker isn't automatically a work truck. But if you see a gooseneck ball plate cut into the bed floor, a weight distribution hitch, or a commercial-grade brake controller, ask hard questions about what it was pulling and how often.
2. Engine Selection and Known Issues by Generation
The F-150 has had several engine options over recent model years, and each has its own reliability profile.
- 3.5L EcoBoost (twin-turbo): popular and powerful, but check for carbon buildup, intercooler condensation, and oil consumption on higher-mileage examples
- 5.0L Coyote V8: generally well-regarded, but 2018–2020 models had documented oil consumption issues — check for excessive crankcase pressure or blue smoke on startup
- 2.7L EcoBoost: very capable for its size, check cylinder head bolt issues on 2015–2017 examples
- 3.3L naturally aspirated V6: the base engine is reliable and often overlooked — good pick for light-use buyers
3. The Aluminum Body: What It Means for Inspection
Ford moved the F-150 to a military-grade aluminum body starting with the 2015 model year. This reduces weight and improves fuel economy, but it changes what damage looks like and how it's repaired.
- Aluminum doesn't rust, but it does oxidize and can show stress cracking around impact zones
- Paint thickness gauges behave differently on aluminum — our RideCheckers use equipment calibrated for both steel and aluminum panels
- Aluminum repairs require specialized equipment and training — improper repair is more common and more consequential than on steel trucks
- Look at the seams and rivets around bed sides and cab corners for any signs of pulling or improper re-installation
Where We've Seen This in Lake County
We've inspected F-150s from private sellers in Gurnee, Round Lake, Zion, and Grayslake. Commercial-use trucks appear regularly in listings near Waukegan and North Chicago. Knowing the vehicle's actual use history — not just what the Carfax says — is the difference between a reliable work truck and an expensive liability.
RideCheck covers all of Lake County. If you're considering an F-150 — or any truck — book your inspection before you move forward. We'll give you a complete picture of what you're actually buying.
