 I've had no problems with my Frontier 
so far. My truck already has over 
30,000 miles in less than one year. I 
tow a Mastercraft ski boat as well as a 
16ft. enclosed motorcycle trailer and 
find that the Frontier has more than 
enough power. The gas milage suffers 
when towing. I find that I'm averaging 
18 mpg around town and will drop to 12 
to 14 mpg when towing heavy trailers.
