Just had my clutch replaced in my Toyota Tiger truck. Left the dealer and charged up a nearby hill to check the feel, changing gears rapidly. Each time there was a big clunk as I released the pedal. This sound (and feel through the steering wheel) is a little less after a few days. When I carefully and smoothly shift, no sound or clunk. Should I ask the dealer to adjust the clutch? I don't have a lot of confidence in them, maybe it is better to leave it alone since they could make it worse? Appreciate your advice as I am not very familiar with the fine points of this situation.

There are a number of ways to botch a clutch job from under tightening the bolts that hold the hat on the flywheel to incorrectly bleeding the hydraulics. Go to an independent shop and have em check.
