I owned my Tundra for 15 years. It's only the little 4.7 liter but it has almost 250k miles on it without anything more than routine maintenance. The big 3 don't typically have trucks that can last nearly that long without some repairs along the way. I would like to have a another long-lasting reliable truck but here are some numbers to consider. I figure I will be towing approximately 4,000 miles per year. If you take 4,000 x 15 years that is 60,000 miles. Let's say a typical mpg towing of a gas truck to be 10 mpg. So 60,000 miles divided by 10 mpg is 6,000 gallons. Taking an average gas price over 15 years of fluctuation of say $3.50/gallon. 6,000 gallons x 3.50 is $21,000.00 in fuel. A 20% savings in towing (21,000 x 20%) is a $4,200.00 savings over 15 years in fuel vs. gas. Now you can get a fully loaded truck for about $10,000 - $15,000 less than this diesel. You also have to consider that it is a supposedly well-built Cummins. However, this is it's first trial year out - let's not forget the Duramax's first year disaster. It also had aluminum heads but technology has come a long way too. I am just still completely undecided which direction to go here.
