Being used on my 5th wheel Rv. **Q: Will this tank fit under the standard hard covers, that are normally. used to cover the 20 lb tanks?** A: It's a 30# tank, so it is going to be taller than a 20#. If your 20# tanks are the same height, they still will be skinnier than this 30#. I would suggest looking somewhere that carries these tanks, and view them in person if you are trying to place them in a particular spot. **Q: Where is this tank made ?** A: Made in Thailand ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works. *by G***G on January 24, 2026* Great.
