I think you can get by with a gas tow vehicle if it is rated for the trailer and you tow mostly on level ground. When you travel in an area with a lot of big hills or mountains is when you really appreciate the power of a diesel. My current tow vehicle is a 2005 Dodge diesel with the 6speed standard and 4.10 differential. I wish I had bought a diesel years ago. My gas trucks didn't have enough power, gas milaeage was terrible and I burned up several transmissions. I don't think the automatic transmission in the Toyota will last long towing. If my wife forbid me to buy a diesel I'd buy 2 just to show her who's boss. I guess that's why I'm not still married.
