How can you tell if you have the snow plow prep? I have a 2013 F250 FX4 ult lariat, and it looks level to me. I measured the top of the wheel wells and its 41" exactly front and rear. anyone else measured theirs? I have some 20x9 Fuel Maverick black and milled +18 offset on order, probably going with 35x12.50x20 cooper st maxx. Going to wait until i have them mounted up to see if they rub before I order a level. For the guys whose truck already looks level, anyone use the 2" spacer in the front with the 2" lift block in the rear?
