My truck only has a 14 gallon tank. That doesn't go very far considering I generally fill about 12 gallons. It appears as though the pickup (short wheelbase) has the same chassis as the Rodeo. But the Rodeo has a much bigger tank. Has anyone looked into the feasibility of doing a tank swap? I'd love to hear your idea... I'm planning some long range trips this year and filling up every 3hrs of driving won't cut it.
