Luckily, it's still under warranty,just in case. I wasn't sure if this is normal in trucks, it's a 2007 dodge ram quad cab with 28k miles. When I have weight in the bed, it is so ridiculous even over small bumps it squeaks. I'm pretty sure it's the leaf springs, because when i move up and down over the speed bump, you can hear it move with the truck.
The threads have nothing to do with it and no amount of sealing them will solve the problem. That connector pipe has 'flare' fittings on it. The threaded nut only serves to press the flared end of the tube tightly to the beveled end of the connector - it is this tight fit that seals the connection. Take it apart and look for a scratch on the bevel of the fitting that is part of the heater - or a scratch on the flare inside the tube. One or the other may need to be replaced.
mike is on the right track. i suspect that you are putting a flared flex connector on a standard pipe. you need the flared adapter on the pipe for this connection
After my new furnace was installed professionally, I smelled gas. I called the gas supplier and they came out. He used pipe dope on all of the connections. He said that teflon tape is no good for gas. Take apart the connections and clean off the tape. Use pipe joint compound and re-assemble.

Teflon pipe dope are interchangeable in most cases (except on threaded plastic fittings) and using both on the same fitting is just fine. It goes on male threads, not flares. What you should consider is that gas is flammable and can be explosive in some circumstances. A plumber will probably be able to fix if within the minimum charge time frame. If you aren't familiar with the materials, you might never get it. Is it really worth saving a few bucks over? And, for what it's worth, I would be cautious with a 'vent-free' gas appliance. I would strongly advise getting a CO detector if you're going to use it.
