tank rack

Ever since I was certified two decades ago I have used a junky old pallet in the bed of my truck to secure my tanks. The only good thing about a junky old pallet is that it is free and easily obtained, beyond that just about every other aspect of it sucks. It's not deep enough to stack two tanks...

Little help... I have a 26ft. Regulator and the boat has bolsters all around the boat. I have a space under the gunwales that I can mount to but it’s to deep to flush mount. I’ve been laying tanks on their backs for years but it takes so much space. We usually do 3 tank dives 4 people...
