It depends mainly on if you get single, extended or 4 door. Also on if you want to spend the extra time and money to order a custom vehicle. When i purchased my new 2011 GMC 1500 last year i was rather annoyed to find out that both GM and ford do not offer anything larger than a 5.8' bed on a 4door full size unless you special order.....but if you go down to extended or single cab, then 6' becomes the standard on lot size...pretty lame.
But if you have a for sure 6ft bed, then yes it will fit. I fit my 2001 Foreman 450 4x4 in the 6' bed of 03 mazda pickup with the tailgate closed. Once i put ITPs on it, i had to deflate the tires a little tho.
