The Tracker/Sidekick/Samurai is classified as a "light truck". All of mine have been registered and insured as such in both California and Michigan, I'm assuming those are not the only states and that it's a federal classification of some sort. Yes an F-150 is a serious truck, but that's a different class of truck. But a 1-ton & F-150 and Tracker/Sidekick/Samurai are all built the same way. Body over solid frame so structurally they are the same, size wise....that's a different story.
The Geo tracker is the truck of the Geo line-up.
Mine has 235/75/r15 BFG A/T KO's at 40psi, no lift at all. I have a 16v motor, with the 1990 5-speed (with a lower 5th gear than later models) hooked to that motor is a K&N drop-in filter with a fully open air box mod, and the Calmini muffler on an otherwise bone stock exhaust system. I average around 25mpg hwy, 27 on a good cool day on completely flat surfaces. doing the speed limit (around 65 to 70 mph)
When i lived in Los Angeles where the freeways go up and down plenty of steep hills, and the average summer temp is 87 to 100 degrees outside I averaged only 23 to 25mpg's I could go up a hill and try to keep up with traffic and literally watch the gas gauge go down.
