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.
We took about 1/2-3/4 hour to go though our but it was or 3rd trailer so most everthing was the same.If it is your first then expect to take some time.Enjoy and welcome to the "family" .
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.
