Or just disconnect one tank and hook your hose directly to that without using the regulator on the RV.
OR just don't bother at all. :D None of the trailers we've owned has had a low pressure gas feed plumbed to the curb side of the trailer so I instead T'd one of the tanks and would run my unmodified Weber Q and stand alone Coleman stove off one of the legs while the other leg still fed the trailer. The issue however with any of these methods in which you draw propane from a trailer tank is you'll have a hose lying on the ground that someone
will eventually trip over so I ended up ditching it all and instead run my Weber Q with a stand alone, lightweight 5 lb tank and my outside stove with 1 lb canisters. K.I.S.S. :B
