A collective vertical tank has a plurality of tanks and stabilizing and weight-distributing connectors. The connectors are adjustable to provide an adjustable footprint of the collective tank. A stabilizing and weight-distributing connector for vertical hydraulic tanks includes a first connecting member attached to a first vertical tank and extending away therefrom, and a second connecting member attached to a second vertical tank and extending away therefrom. The second connecting member defines a central passage adapted to receive the first connecting member therein. A locking mechanism secures the first connecting member within the second connecting member.
