Banging noise

[thehippie]

I have a 2018 pacific coachworks fb29xl toy hauler. Sometimes I hear banging noise underneath. Not sure but the banging sound could come from any of the tanks but more likely the gas tank? Is that common? Is it bec from pressures? I have this sound ever since buying it. Anyone experienced this?

Good grief....
The other posters have nailed down some potential causes for the "banging." But your original post left alot to question.
While parked, while driving, when hitting bumps, only when you n Mrs Hippie are gettin hippy, front, back, morning, night, after gas tanks are almost empty, only on Tuesdays?
That's what I was gettin at.

wow

basement?

I'm glad you found it funny... that was the intent.

Basement.. + Outside storage (under the floor of the RV) of course I've never heard it called anything other than "Basement storage".

A very common sound from toy haulers comes from the fuel tanks. They are notorious for venting badly.

I have one tank for my generator and another for my fuel station. The gen doesn't draw fuel very quickly, so it doesn't usually bang. The fuel station will bang every time I pump gas out.

The solution is to crack both gas caps and leave them cracked to vent for the whole time you're camped. This especially helps if you have high temp swings since the fuel tanks aren't insulated if you have an enclosed belly.

thanks. I’ll try it next camp.

Sorry no clue It is possible the fuel tank can bang, among other things. If the fuel tank builds up a vacuum and then it sucks air it can bang.

Various parts (Drive shaft, exhaust) can also bang and more.

wife? where?

Does the banging occur when the furnace is running, or shortly after the furnace turns off?

We have a 2014 Pacific Coachworks Powerlite 23FBX toy hauler travel trailer. We have an occasional bang occur while the furnace is active. I believe it is the sub-floor heater duct making the noise. The metal ducting expands as it heats up and makes a thumping or banging noise. After the furnace shuts down, the ducting begins cooling and makes another banging noise as it contracts. I just ignore it -- not worth the effort to fix it.

banging was more pronounced when the trailer was new. After a year, now, the noise isn't as prvalent but still nas those noises once in a while though.
