I am looking at buying this truck, It is 4x4 has 270k (not bad for my area see them up to 450k) with the 5.4L Triton. Has a fifth wheel. Basically are there any inherent issues with this year of truck I know about the spark plugs blowing but is there is anything else I should be aware of? Haven't been able to find much on the 98 f250, from what I read it was a transitional year. Are the parts more expensive because of that?
