WE have a 2015 Redwood 38BR and we have been having this smell(smells like propane, but the sniffer says there is no leak) off & on for the 2 years we have owned it....it has gotten really bad now & making me sick....anyone else have this issue?

There was a leak in the regulator at the curb side tank. We smelled propane in the bath and the bedroom, but the detector did not go off. Bought and used some propane detection liquid and found the leak. Soapy water will also do the trick, but the stuff we bought is thicker and works longer. The regulator Redwood and most RV manufacturers use is not the best.

Thst would be my suggestion, fill a spray bottle with soapy water& spray all propane fittings starting with the changeover valve on the streetside & the small regulator on the curb side. If its not propane check the back flow valve under the bath sink on the black tank flush line or the vent valve on the drain to that sink, sewer gas smells like gas/rotten eggs.

Same situation with propane regulator on curb side tank. The diaphragm fails with a pinhole leak. Need to replace it. A new one costs about $16. This is a known and well documented problem on Redwoods.

here is the write up about tis problem and fix from our Technical Library. If you go there the article also has photos.

Problem
Owners have experienced failure of the curb side LP gas pressure regulator. Propane gas leaks through the vent port, probably caused by a ruptured diaphragm. This causes a rapid loss of propane and presents a potential fire hazard.

With an open end wrench (SAE) or a nut driver, remove the two screws at the top and bottom clamps that secure the regulator to prevent it moving. The threaded connectors are underneath these clamps
Clear the clamps from the threaded connectors
Hold the regulator steady with pliers or a vice grip, then using a wrench, disconnect the lower pigtail from the bottom of the regulator. Repeat the process disconnecting the top line, which goes to the roadside regulator. Note - Redwood used some “goop” to seal the threads, so they may be a bit tight to dislodge.
Apply yellow (not white) Teflon tape counter-clockwise on the threads of the lower pigtail and the cross connection hose, being careful not to put any in the interior, which could contaminate the propane system.
Install the pigtail on the regulator side marked “in”, and the hose on the side marked “out”
Place the new regulator in the approximate final position and connect the pigtail to the cylinder
Open the valve on both tanks. Conduct a thorough leak test, using a water/soap solution, which can be applied by a spray bottle or brush. Coat all the threaded connections (top and bottom), looking for bubbles, which indicate leaks. If a leak(s) are present, take the connection(s) apart and start again with new Teflon. When you are doing this, you might as well check all the connections and regulators for leaks.
When the soap test reveals no leaks, re-install the clamps to secure the regulator.

Also suggest you check your battery vent hose. Ours came off and we had a smell that was very similar to propane.

When my battery burnt up I had the same smell. Also when my vent under the bathroom sink quit working as well.

If you eliminate the propane system as a source of the smell, I would start looking for a sewage smell in the bedroom area.

On our 36RL we have had bad vents (one under the sink and another behind the closet wall that services the clothes washer). As a temporary test, duct tape the vents closed and see if the smell disappears. I'm not sure why RW installed these vents as both drains are very close to the waste tanks, I was told that the regs for plumbing in houses indicate that you don't need a vent if one is located within 12 feet of an existing vent (the vent stacks for the tanks are within that range).

My duct tape solution has worked well for a few months now!
