I'm looking at buying a 2nd gen s10 and wanted to know if it is possable to bag it and still keep my bed pretty empty, as i dirtbike and would like to be able to use the bed. I was lookin at air ride technologies roadgrater, or 3-link system. I know I'm going to have to c-notch into the bed i just didn't want to have a monster notch. Any advice would be helpful thanks.

Get a trailer.
the hitch will toss sparks too when you slam the back driving down the road so it works out in two ways for you 

You can mount the tank and compressors off the frame to get them out of the bed. A couple companies make s-10 gas tank crossmembers that raise the stock tank so you wont trash the factory tank. Also do a bit of research on the backhalf, IMO you can do better for less money then the roadgrater
