This is my solution. It's cheap, easy, works great for tanks, and for any other cargo: DIY-ish pickup bed rails for securing tanks
If you aren't strapping them down, you are asking for disaster in the event that you are in a bad accident. Which if I'm completely honest, I sometimes do on low-speed trips around town.
Whenever you lay them down in the bed, whether by themselves, or with noodles, or in a frame, or whatever -- lay them with the butt facing the cab and the valve facing the tailgate. This will help protect the valve, since you are much more likely to slam on your brakes than you are to be rear-ended, and you would rather have an impact on the bottom of the tank than on the valve.
Bas at VIP Diving loves my rack. He adopted some of its features and made some prototypes. Not sure how they worked out.If the truck rental agencies only provided racks so nice!
Is there a strap or two over the top of the cylinders?
Here's mine but I live on Bonaire and dive pretty frequently. My wife has problematic wrists so we designed the flap to allow a smooth slide for the tanks and to protect the area between the bed protector and the tailgate cover. My next truck will have the sprayed on liner that covers all of that.
Not usually. I’m going to buy a new truck soon and I’ll either modify this rack or make a new one and I’ll probably make it a bit more secure. With hundreds of rental trucks for divers on the island I’ve never heard of a single tank incident but being careful never hurts.Is there a strap or two over the top of the cylinders?
