Had a 91 Toyota ext cab 4x4 with 4 cyl and 5 spd. 22 mpg all the time be it city or hwy. Ok if you have little kids but the backseat wouldn't handle them if they are getting older. Awesome truck, just needed more room.
Then had a T100 with the V6. 17mpg hwy and 12 towing 5000 lb trailer. Great truck but not enough power.
On to a 2000 Silverado with 5.3. 17 mpg hwy and 10 (if lucky) towing the same 5000 lb trailer. This truck was a POS to boot and was in the shop at least twice a month. Shoulda got the Tundra.
Now-2003 F350 with 7.3 Diesel, 4x4 crewcab SB. 18 mpg hwy (have gotten 23) 17mpg city, and 10-11 mpg towing a 13000 lb 5th wheel. Does everything I need it to except cannot hold a candle to the Toyotas for reliability. Still waiting for that Tundra 1 ton crew dually with a diesel...........................
