I believe the XLT comes with carpet VS vinyl on the floor, and some fabric in the door panels.
Essentially a trim option, but if you want any other options, you're ususally forced to go with the XLT.
XL=work truck base model
XLT=more of a personal truck
MY XL looks VERY bland on the inside, but I can hose it out too😀
BTW, they (Ford) plans to sell the 03' model next year too, alongside the 04' (which shares virtually no parts with the previous model). IIFC, they're calling it a "Heritage model or something"
