Did I buy a diesel because I HAD to? Nope. I bought one because I WANTED to. Yes I could tow my trailer with my 07 Tundra. But I can say without batting an eye that towing with my new truck is no comparison at all.
I thought I knew what it meant when people said "it doesn't know the trailer is back there." Well I can tell you that towing a 4,000 lb trailer with a 3/4 or 1 ton diesel has given a whole meaning to that statement. It's amazing!
Yes diesel is about 10% more than gas but I am getting 20% better fuel economy unloaded and 30%-40% better towing.
So I guess you can call me silly then. But is reality is it any less silly for us to buy a new $10,000+ sled every couple years?
