It's not hard. I very much like the idea. I think MTMike got one on a shortbed. Check out the crew cab threads. If I can't get to liking this K5 I may go crewcab.
Tonight I put her on a 450lb or so diet. Top ?, doors 85lb ea, Tgate 116lb, hitch (bent it all up today) 45lb, hood 65lb , heavy floor mats 20lb, cheesy grill guard 35lb, anything else that i could unbolt that was not necessary. Part of why I rolled today was cuz she was too heavy and sunk in the sand on a sidehill. We'll see how she does tomorrow.
