Someone makes pickups with a bed smaller than 8'?!?!?!?!?! wow! who would a thunk!
Sounds kinda dumb to me, wish I could get a 10' pickup bed frankly!
But as far as maneuverability goes......... get the truck with the most wheel cut. My 188"WB Navistar can out turn my 88 155" gm ext cab. Not quite on par with my reg cab truck, but it will out turn pickups really easy! Take the same rig with a 45 degree vs the 55 degree, and the 45 is over 15-20 wider radius!
