sorry for you experience. When we picked our up, they ONLY made morning appointments for initial walk through and told us to expect to take at least 3 hours and the salesperson would go through everything with us. Sales guy staid with us and went through stuff with us, DW found a few very minor items to fix. After almost 4 hours we had punched through the list, went to lunch, came back and checked out the items to be fixed and then were on our way.
they suggested that we could video tape any or all of the PDI if we wanted to as reference.
I'd go back to the dealer an insist on scheduling time for a quality walk through.
He and us went through every drawer, door, window, drape, appliance, etc. to make sure everything worked including things like hooking up to cable tv and verifying it worked. Verified fridge on propane/gas, same on WH, filled all the tanks then emptied them, crawled around on the roof and under the trailer and went through how to manually operate the slides.
they had a checklist of items to cover that was even more detailed than the one I had as a reference and was using as my guide. At no time did we feel rushed at all. Salesman was slow and methodical going through everything making sure he was covering everything.
