 Mine is PreRunner V6 Quad Cab Longbed. The rails in the bed are perfect for an Extang Black Max Tonneau.  Plenty of room and comfort for family and big dog on trip. Longbed perfect for luggage to ladders to tree limbs going to the dump. Best mileage is 23 hwy, but driving fast loaded can get it to 18. No problems of any kind after one year and 15000 miles.  I didn't realize it when I bought it, but the LB has a Suburban size wheelbase, and therefore a large turning radius, which makes small spaces tight. Seating is comfortable on long trips and provides good driver support. I'm 6'1" and 190. Vision all around is good. Unless you deal with small parking spaces every day, buy the longbed.
