Furnace in 2021 Salem Cruise Lite 178dbfs

So my furnace works fine but it has this clanking sound when heating up and cooling down. Kind of like a hot skillet cooling down, how it clanks. It’s quite unsettling, not that these furnaces aren’t already loud. Is anyone else experiencing this. We’ve have RVs for a while now and this is a new noise for us.

Does it sound like metal hitting metal, such as the fan hitting a shroud? If it's just a ticking sound, it may just be the metal expansion as things warm up.

I feel that it is the metal expansion but it’s ridiculously loud when turning on and off.l, more so that previous trailers we’ve owned with similar no-duct heaters.
