Melbourne, clunk...

When I drive out of a driveway, from one level to another level, or into or out of a parking lot onto the street, something under the unit goes clunk. Maybe not a clunk. But it's like there's a bolt, maybe a big one, that is slightly loose, allowing whatever it is that it's holding together to shift a fraction of an inch.
It's been doing this for a year or so and now seems to do it more often.
I've slid on my back under the entire unit, with a wrench, tightening bolts here and there. Nothing has made a difference.
It's a 2017 Jayco Melbourne 24M, with 32k miles.
Any ideas....?

My guess you have a worn swaybar linkage. Sometimes they fail with a short life. I have replaced them on my TV twice now. Once in the first year. When they fail, I hear a clunking sound.

A loose bolt to me is higher pitched sound, kinda like a ringing.

I found the source of the clunk. Actually, a mechanic did.
It was the Helwig sway bar I installed. The bolts were not tourqued tight enough.
My bad...

It is also recommended to retorque the leaf spring u bolts on the axle. I asked the dealer if this was part of the A or B service and he said no. Your dealer may have a different policy. Very easy to do yourself.
