Clutch slipping?

My 2000 F350 XLT 2WD 6-speed manual transmission seems to have a clutch issue.
It has 93,000 miles on it and has towed a 5th wheel most of its life.
After arriving down south here for the winter, I noticed that in OD or 5th gear, if I mash the pedal the RPMS will rise, back off on the gas, and it dips back to where the RPM should be. You can hear the change in the engine. This is without pulling any weight. I notice it going uphill too, mash the pedal in 4th or 5th, engine RPM goes up.
Shifts just fine.

I am taking to a reputable Transmission shop here in Oceanside, CA to have them look at it. We don't leave with our 5th wheel to Texas until Jan.

Could it be it just needs an adjustment? It's all stock except the airbags I installed.

Sounds like 99.9% it's going to be the clutch. Textbook symptom....I have a South Bend clutch in my truck and am very happy with it. One thing I didn't use from their kit was the kevlar pilot bearing, instead using a timken roller bearing. Kevlar is a terribly abrasive material and a horrible bearing choice.

Update: The mechanic tore it apart and put in a new clutch a d clutch kit. The clutch was ok but the pressure plate had hot spots and the pilot bearing as well as the throw out bearing were very very worn, that was the noise I'd hear when pushing the clutch in under load (clunk!)
Oceanside Transmission resurfaces their flywheels in shop too.
Good now. I wont have to worry about breaking down pulling our 5th wheel thru the southern states this winter !
$1426 ($888 for clutch kit with bearings a d $537 labor)
