Ok so I had a sportsman 2 and it fit perfect in my tacomas bed with the tailgate down. Now I know the bass raider will hang off but I'm wondering about the width. I would like it to fit in between the wheel wells and the specs online show the width measuring from the seal. Does anyone know the width of the bottom of the pontoons since it tappers down? thank you. 

I haul that exact boat in that exact truck.  It fits perfectly.  48" pontoon width, I think.  Whatever the dimensions are, it was designed specifically to fit between the wheel wells of midsize pickups.

Sold my Tacoma 2 years ago but as basscrusher says, it fit perfectly (width-wise).  It will not slide from side to side at all.
