gas gauge stuck?

try driving it HAHAHAHAHAHAHAHAHAHA
does it drop when you turn the truck off.
try tapping repeatedly on the cluster with your finger. pretty firmly. this unsticks my speedo in hot weather.
try one or two bottles of Chevron Techron fuel injection cleaner. sometimes that removes the corrosion thats can cause a problem in the sending unit.
if that doesn't work, you'll likely have to remove the pump/filter/sending unit from the tank and investigate - and likely replace the whole blooming expensive unit.
