I just picked up an 05 F250, because my 02 burnt to the ground monday. This is my first deisel and i know nothing about them. First i can not find where the keypad numbers are for the door. I need to find where is the plug to plug my electric brake box for my travel trailer. Is there any do's and dont's with these trucks? What about programmers, some say yes and some say no? I really want a programmer for the fuel mileage. What about oil changes, how many miles in between and what type of oil to use? Sorry for all the questions, i just want to enjoy the truck and do whats right. Feel free to add anything that i might need to know. Thanks for the help Lil John:beer:
