Take spare water jugs,64 gal will last 3 days if your conservative. I read something on here where the kantleak valve can suck water into your tank? Not sure! If not you will need a way to pour the water. Some folks crack there grey tanks but I've never had that trouble. Usually anything longer than a week the event planner will have someone avaliable to pump your rig out. Oh take gas for your generator. I take 3-4 jugs for a 5-7 day show for AC if heat take spare propane or have the availability to get some. I take 3 jugs for water. Now you can take less but will have to make runs all the time to get there things. If it's a couple days you will be fine
