Can I use a propane dryer and full size range on a 40# cylinder?

You can buy a two stage regulator which will screw into your propane tank. You can adapt the outlet to your gas line. The regulator is about 60 dollars available at camping supply stores, not home depot Walmart ect. You will be swapping tanks lot and will not be able to use both appliances at the same time due to low pressure from the small tank. Be careful. You may want to call a proffesional.
