This product works well as a soft cover. It stretches to cover both 40lb tanks, and has a two piece wood support for the top. The zipper is in a perfect location for turning the tanks on or off or for switching from the left tank or the right tank to the other. It is very lightweight. The only two things I don’t like are: 1) condensation can form inside the cover in humid areas; 2) the two wood support boards can be very finicky to deal with.
