The F250/F350 with the 7.3 Diesel by (International T444E) is easy to repair and has simple mechanics behind how it functions. It is a truck that pulls well, if the transmission is upgraded and will last a long time. No emission problems or DEF issues. There are a variety of after market parts to complete repairs and maintenance, unlike new trucks that stop having parts made after 3-5 years. The truck has been around long enough and forums address almost all issues. Transmissions/torque converters are the weak point ($5-8k) and always keep a Cam Position Sensor ($20) in the glove box with a 10mm wrench. Another common maintenance item is the injector control module. I recommend adding a fuel rail cross over to prevent air getting trapped in fuel system and drilling out the oil drains on the top of the heads to allow better draining back to crank case.

If you hear anything bad about the 2003 ford f250 just know it's not true. Currently, mine has 251,242.9 miles and it runs just as good as the day I got her. My brother has the same truck. He got it in 2004 and his currently has 1,487,675.7 miles and has no problems. Best truck I've ever had 10/10! Just make sure you change the oil and take care of it!

Only has 98000 miles put a lift and bigger tires complete pooch tyranny went out spark plug broke off in the head switched to a 4.56 gear still no pulling power went with a tune still just a good looking truck that I don’t trust at all
