Agree with all the others. it depends how far you want to (what they will call) nit-pick.
My experience over 5 new vans has been that the electrics can be a weak point - not one of the 5 had the TV booster connections made off correctly. Others had the wrong rated fuses in the 230v. services and appliances, Omnivent fans that only worked with the reading lights on, Truma space heater full of woodshavings which would have caught fire if the gas had lit up correctly - it didn't the igniter lead was disconnected.
Take a mains socket tester and check the incoming mains is correct polarity (particularly with a continental van); check the tyre pressure and that of the spare before you drive away - I've found pressures at least 40 % low.
Check all the window blinds including the Heki close, stay closed and retract correctly.
Sorry to sound a wet blanket on what should be a very enjoyable experience, but I've seen all this and more on 3 different makes of van.
The dificulty is, if the dealer has not done the PDI correclty, what confidence can you have that he will do so if you complain ?
