Have an '12 Lariat, 90,000 miles. Great engine, great truck.Never been in shop. Engine pulls like no other. Averages 16.5 running around, maybe 10-12 towing.
As previously mentioned, you're gonna need to 'bag it if you are going to tow heavy. 300-400 bucks and a few hours work.

Democracy is not freedom. Democracy is two wolves and a lamb voting on what to eat for lunch. Freedom comes from the recognition of certain rights which may not be taken, not even by a 99% vote.
