Gilda, the portable propane
tank holder is called a Tank-Genie
- I purchased it at Canadian Tire a few years ago. It can hold up to a 20lb propane
tank or a large water bottle. I like it more than some of the other portable holders I have seen due to the fact it has a much larger base which provides a lot more stability. As I mentioned its never moved an inch when transporting even when stored on smooth fiberglass floor of the shower in the trailer.
