Back Now lol
I have enough room in the back of the trailer for a 250 ltr tank, 100m hose and reel, and battery with my pump box, there is no room, even to put my backpack, I have to stick that in the car, so with the swivel it can be strapped to the top of the tank or sit it on the floor.
I did look at those hose lock things, but there would be no perminent place to install it, and would have been a lot easier.
