My wife used rubber material for shelving, which has worked well along with a Velcro strap .
I found a company who can build the antenna coax cable we need, $35 for 35 ft.
I found a company that makes an LPG gauge that sends the data to your phone. I have it installed and we will see how it operates. It has senders that attach to the bottom of the tank by magnet, it shoots up vertically to determine level, also sends a text at an adjustable alarm point for low level warning.
Also installed a new SeeLeveL console that Bluetooth connects to the phone, very handy for working outside with tank draining and filling.
