We bought a 2004 Chevy dually (Ziva) 1 1/2 yrs ago and is evil on gas

Have a 1964 Jeep Gladiator stepside pickup we are going to restore this year and see how she does. I am "so over it!" with all the electronic/brains mess that will malfunction if you sneeze! Leaving us and our beloved horses stranded on the road side for something we cannot work on ourselves.
So, Gladiator (Baby Ziva), here we come !...and you better pull and stop! My 2 horse slant Exiss with Sweet Mare Mariah aboard
We are also great fans of the older rides! Hubby has a 1955 Chevy Belair as his daily driver! Very Big Cool Factor
