Bumping under drivers feet?

[homeless]

I have a 2000 itasca suncruser Ford. I have a bumping under my feet when driving. I have had front end inspected by a macanic that said he doesn't see a problem. I am thinking maybe related to body and frame. But I can not see any rub or signs of loose anything!
Anyone have such issue before?

Does the bump change with speed or rpm changes? Does it disappear on smooth roads? Does it change if you put light pressure on the brakes? Is something rolling or bouncing around in a storage compartment? Those are the things I would check first. Then get under and grab parts and shake them, looking for a worn bushing or loose fastener.
I don't know your mechanic, but I know one locally who told me what I wanted to hear just to get rid of me. When I checked his work the bolts all had unbroken paint on them. Since there was no fee, I had no gripe, and proceeded to fix it myself.

Despite your mechanics search, I recheck" shocks, track bar, sway bar, spring ends, and drag link....

It's not consistent at all some days nothing and sometimes seems to happen as the rig rocks. Sometimes does it from starting to move.
I was hoping someone might have similar issue?

Remember a similar problem a long,long time ago and as I recall it was some sheet metal near the wheels that was vibrating. Think I found it by taking a rubber mallet and thumping on everything.

I had a slide out of adjustment once. It caused a heavy thump when hitting a pothole or something similar. Sounded like a hammer blow below the drivers seat.

homeless,
my front leaf springs move from left to right and vice-versa when turning sometimes. I can feel and hear it for sure.
greasing the zerc fittings seems to moderate the noise.

Last year, there was a rolling, clinking sliding sound below my feet. It happened intermittently at starts, stops, some corners, some hills, but not always. I finally convinced myself that it was a sliding linkage of some nature. I spent hours on a visual inspection...then found the lug nut wrench and bar where I put them.

In the compartment below my feet.

I would take a hard look at sway bar bushings and end links. Make sure the bushings are intact and bolts are tight. The rear sway bar bushings are known to wear out, replace them with new poly bushings if they're done for. My left rear mount was hanging from the bottom bolt when I looked at it, bushing was torn up, bracket bent, 9000 miles on the odometer.

I know you said under the driver's feet, but sometimes these noises can transmit through the frame and what not, and sound like it's right there even though the problem is 20 ft away.

Torque for the sway bar bushing mounts and end links is 66 ft lbs. they are known to clunk if not tight enough.

If all that is good, look hard at shock mounts and spring hangers. I don't know the torque on those, but it's considerably more than the sway bar components.
