Under passenger seat size?

I'm visiting family for the holidays and don't have my truck but bought a 118 piece craftsman set just now with the intentions of keeping it under the passenger seat, could anyone give me the dimensions of the area under there so I can make sure it fits or if I have to take it back and get a smaller kit

 

There is basically no room under there because of the ecu / airbag box under there , you can fit stuff behind the rear seats in a DC though

 

'05, no side airbags... there's more room, but I'm not sure if there's enough for the tool set.

There is enough room for the smaller amplified sub boxes, but it likely wouldn't fit going in from the front. Access cab would have to go in from the rear floor, or slide the seat forward on an RC.

 

Those spots are already used up by my Toyota emergency kit, 4 ratchet tie downs, extra fuses, rope, 100ft extension cord, hand warmers, and a 12v air pump for my air mattress/kayak, I know my bigger tool kit was a close fit so I'm hoping this one will fit

 

Well there you go , I didn't look at the year of the OP's rig
