Hello, I am new to this forum and discovered this site while searching known problems for this year vehicle. Anyways, it looks like the are a lot of educated people who might be able to offer some input on a 2006 Expedition King Ranch 2wd 5.4 L that I am looking to purchase. The Carfax are clean, the mileage is 92,000. The condition seems to be average to slightly above average with little to no interior wear or stains. I will be using this as my main vehcile and will also use it to tow my boat(4000-5500lbs depending on load). Sometime the towing will be over 250 miles each way but usually only 45 miles. The long haul will only be 6-7 time a year at that distance. My concern is the mileage and life left of the vehicle with the loads of towing and daily driving I will be doing. I am aware of the spark plug issue and paint chipping issue. The previous owner just had a FOrd dealer due a 90,000 maintenance tune up and everything checked out in good condition. My cocerns are buying this truck and then getting caught up in maintenance/ repair bills in the near future. What preventative maintenance should be done to the truck within the next few miles to make sure I am problem free for the next 40,000 miles? Are there any other known mechanical issues out there? I am negiotating the price now and would like anyone's expertise to what I am getting into and what I can expect. Thank you. Dan
