I have 2 maw-15s and I just bought a 98 K2500 single cab long bed pickup. I've seen it done before but couldent find it in a search. I'm thinking of putting a box in the bed and cutting out the bed/cab walls and have them fire into the cab from the bed. Was wondeing if anyone here has done this or has links to it being done. My biggest concerns are water/out side elements destroying my equitment and also I will be using the truck like a truck and I'm afriad the bed/cab gap will change while off-roading or towing and mess up whatever setup I do...
