Yes, two standard regulators do not play well together. The recommended fix is to remove the Weber regulator if a high pressure connection is not available from your RV. I use a 12' Camco hose that has the correct fitting for the 1 lb male fitting on my grill and a female fitting on the other end that mates with the Extend-A-Stay fitting I installed at our onboard LP tank before the onboard regulator.Hello, has anyone found a good quality RV disconnect hose that attaches to the 1lbs propane bottles attachment. One like would go to a Weber Q1000 portable grill. Would two regulators make it a poor idea anyway?
