i was looking to add a 5th wheel spare to the bed of my truck. i'm running 35's - so the stock 5th wheel is basically worthless to me, so i took it off. Does anybody have any information about putting a 5th tire and wheel assembly in the bed - like those desert racing trucks?

 

Just decide wether you want the flat mount, or one that has the tire at a angle like a desert truck. Then drill the holes, and bolt it in. Pretty simple. It beats crawling around in the mud while offroading, or on wet pavement in the rain/snow.
