my favorite tow rigs would be a chevy 1/2 or 3/4 ton with the pre vortec 350 (throttle body fuel injected) my 92 1/2 ton extended cab got 18 mpg empty and about 15 towing a 17 ft open bow. power to fuel milage was the best ive heard of in a gas truck, though my 96 extended cab 1/2 ton with the 350 (vortec) got about 12 if i was lucky and that was empty. Now im towing my boats with an 86 f250 that has a fresh 460 and c6 tranny( i believe), and it tows fine, has plenty of power, has a custom 4 tone paint job( due to some body work), and it gets about 15 gallons to the mile, ok its not that bad, probably 10 to 12 mpg i would guess, but it gets the job done, never leaves me stranded, and the best part is, i only paid $600 for it. so i get more money to put in the boat. In my opinion as far as new trucks go, other than being grossly over priced in my opinion, they all have good and bad points, just do some research and get the one that fits you best. Brian
