Buying a lariat w502 package, 20 inch aluminum wheels. Need to decide on v-8 vs EB. tailgate ladder or not. Any issues w EB engine? Gas milage/reliability/getting teased by guys w the V-8? Does the ladder thing rattle? Damage easily? Does anyone have the 20 aluminum wheels? If so do they look like the pics on the Internet w the black paint. The wheels at the dealer are all aluminum w/o the paint.
