I have the vent kit. Worth every penny. If you can manage to round up some guys, pull the bed off rather than dropping the tank. Much less chance for bending or breaking hoses and fittings, as well as having dirt and rust falling in your eyes. Half a dozen bolts, and a few wires for lights is all that holds the bed on. I did mine at a wrench day with some guys, we used one of the members overhead crane on his service truck, lifted that bed right off, then the tank is at knee height, you can perform "surgery" on the tank like a doctor!
