AHA!

it makes sense - now the question is 300 or 400 or 500 lbs!

 

I'm sticking to my original answer of 250-300 lbs for your Tacoma...

 

I'd start with three tubes (180-240lbs) and go from there. If you need more, get more. I had eight 70lb tubes and it wasn't enough for my circumstances (too wide a tire, too much hp/torque) and I still spun tires and needed 4wd excessively.

 

you guys rock -thanks

I will attempt to drive up the nearest possible snowy mountain now.

 

well toy you suggested around 600 - loosehead you said 300 - I compromised and have about 400 lbs back there now......she still moves fine and have two bags of gravel in the garage for reserve!

muahahahahahhaahaaa
