GOT the odor of gas smell.

Is the smell inside the camper or outside only? or both?

If you have 2 tanks, turn one tank off completely and open the other. See if there is still a smell after 15 minutes. If not, turn on the other tank and turn off the first. Wait 15 minutes. Is there a smell? If so, it's tank specific.

Now turn on both tanks? Smell? It's not the tanks then. Start with the regulator and start the soap-em-up treatment.

I had a leaky tank for years. As long as I kept the valve closed, it never leaked, or smelled. But when I turned it on, it would smell sometimes, depending on the way the wind blew. I only run one tank at a time and fill it immediately when it's empty, so I basically ran only the 1 tank and switched over just long enough to get the first one filled. I never did replace that tank. When we sold the camper for our current one, I made sure the dealer new the one tank lost propane. He didn't care and it didn't change any value in the cost of the trade. But running on the one tank only, we never had smell. Turn on the other one, and there was (sometimes) a faint gas smell.

Check your tanks, one at a time. It's an easy way to eliminate if it's the tank or not.

If there is a service shop that you usually deal with call them.
If there IS a leak it is a LOT easier to track down with a "sniffer" and they probably have one.

It is not unusual to have some smell outside when first turned ON. The valve stems don't seal perfectly; you need to turn it all the way on to seal the handle.

X2 I checked for leaks too but get that smell when almost empty.

The regulator would be high on my list of possible suspects. Seems like most OEM regulators are not built with a good diaphragm and failures are typical after a few years of use.

Hopefully, someone will post the brand of a durable regulator (if that is the problem).

Mix up some very soapy water or buy a small bottle of children's bubble soap. Use it to check every connection you can find if you can't localize the odor to a smaller area by smell. Also check any rubber hoses and copper tubing for cracks, as well as any iron piping for heavily rusted areas that could have pinhole leaks. Your trailer isn't old enough to expect iron pipe corrosion issues though, so check the easiest stuff first.
