PC if you didn’t remove your door hinge (assuming you removed the doors). The bottom hinge would make a perfect place to use a strap to go around your tanks. Although I’m uncertain how you’d connect it and to what on the other side. There is a guy here in town that just built a food truck and he used heavy straps (like a tow strap) to mount his tanks, and I thought it was a good idea because it won’t scratch up your propane tank and his were very tight. He may have used a ratchet type 2 inch strap on his tanks. Just a thought.
