My vote is stay near the dealer until you are satified all is well.
Rushing or hurrying through the shakedown process is never beneficial.
THis is a one shot deal, once you leave the selling dealer you are on your own.
No one else has more motivation than the selling dealer to make sure your rig is satifactory.
Everyone else down the road will not be as motivated or obligated to assist you like the selling dealer. With that in mind stay close to the selling dealer and hold their feet to the fire until you are satisfied and happy.
