Used Ford Trucks For Sale

Match GVWR and GCWR to the job. F‑250 and F‑350 handle light commercial and trailer towing with pickup beds or chassis cabs. F‑450 and F‑550 move into higher payload upfits like service, dump and small box bodies with 19.5 inch rubber and larger brakes. F‑650 and F‑750 cover true medium duty work with 22.5 inch wheels, heavier frames and available air brakes on many units. Verify axle ratings, wheelbase and rear ratio to ensure you can carry the load and keep the engine in its torque band at cruise.

Ask for the forklift floor rating and crossmember spacing, tighter spacing and thicker floors handle point loads better. Inspect for broken stringers, popped fasteners and soft spots near the rear threshold where dock plates land. Scuff liners should be intact to protect wall posts, and e‑track should be securely mounted. On reefers, examine door sills and seals, look for condensation trails that signal insulation voids, and confirm the unit reaches and holds setpoint under load, a strong box reduces cycle time and fuel burn.

Start with the door sticker for GVWR and GAWR, then weigh the truck as configured, full of fuel and with common tools on board. Subtract scale weight from GVWR to find legal payload, do the same at each axle to avoid overloading the front or rear. Aluminum or composite service bodies and liftgates can save hundreds of pounds compared to steel, but confirm they meet your durability needs. Keep wheelbase and overhang reasonable to maintain axle splits and turning radius.

Aluminum Super Duty cabs resist rust, but steel frames, crossmembers, spring hangers, brake and fuel lines can corrode. Look for bubbling paint, deep scale and flaking near body mounts and rear frame kick‑ups. Inspect DEF tank brackets, battery trays and ground points, and check for trapped debris in frame channels. On box bodies, examine rear corners, door tracks and thresholds. Documented rustproofing, clean undercarriage photos and maintenance records are good signs.

Diesel engines like the 6.7L Power Stroke excel at heavy towing, PTO work and high annual miles, with strong low‑rpm torque and better fuel economy, but they add emissions complexity and higher service costs. The 7.3L gas V8 shines in lower mileage, stop‑start or cold‑weather routes with simpler aftertreatment, quicker warm‑up and lower acquisition cost. For F‑650 and F‑750, Allison automatics pair well with either fuel, pick based on duty cycle, idle time and the availability of qualified service in your area.
