somewhere in here is a PDI [Pre Delivery Inspection] guide...several pages long.
therefore, I suggest taking it, a note pad, pen and plenty of time.
Have the dealer go through EVERYTHING....i.e., does fridge, water pump, heat, etc.actually work.
It took almost 8 hours to go over everything in my 5th wheel.
I suggest to give the dealer a "heads up" as to your plan, whentaking delivery.
I would take some pictures. By the time we went camping, after buying in January, I "forgot" some of the switches and procedures. anything to help the memory will be an advantage. And you can always ask here.
