I've been checkin this site out for bout a week and I like it alotso idecided to join. I just bought an 03 8 months ago and I have to say that although I bought the 2.2 for the gas mileage, I think id have rather bought the 4.3. Maybe the 2.2 is ok with the regular cab but the ext cab must be alot heavier and I don't thinkmy gas mileage is all that great. Has anybody had problems with the headlights dimming when you downshift? I thought it was my imagination but someone saw it and confirmed that they did dim down everytime I downshift from 4 down.
