ok so i am looking to trade my chevy s10 for a bigger truck.. i found a 2001 ford f150 ext cab that i like.. but i want opinions on them. it has the 6cyl in it, automatic..about 85k miles on it.. i am wondering with regular maintenance (i am very precise with maintenance on my vehicles) how long the engine would last and if there are any known problems with this year of truck whether it be mechanical, electrical etc.. i thank you all for your help..
