My 2005 F150 Lariat CrewCab has 110K miles. Original owner. Use every day in local driving and about 4K or 5K miles per year towing a 7100# travel trailer... Normal oil change and service every 4K miles. Original Plugs, runs like a top... Only maintenance is brake job at 80K miles. If someone is looking for a used one, I would say anything that looks like it has been taken care of and has less than say 100K miles would be a great truck with another 100K trouble free miles..
