I have two 100gallon tanks that are brand new. With 2 saddles and 3 of four hold down straps. Never had anything but a little water in them to test with. I bought the planter with these mounted on it anlready and took them off and set up to pull fertilizer trailer is only reason for selling. Would mount up easy to planter frame or what have you. One is plumbed up to haul water to wash my hands with during planting.  7 eight 5 five six 7 6 one two zero
