Yep, and I wish I could remember who told me that, but it sure makes sense. I haven't seen a dealer yet that doesn't have some spot to let you stay overnight, so make use of it.
Hook up to your tow vehicle, take it to the spot he gives you, disconnect the tow vehicle, set your levelling devices, turn on the radio, and the TV, cook dinner, check the guages on the control panel, clean up, turn on the furnace for a little bit (even if it isn't cold out), try out all the fans. Next morning, cook breakfast, and of course you will have used the bathroom, so here's your first opportunity to empty your waste tanks.
Watch for water leaking anywhere, listen for strange noises, buzzes, hums, or clicks as things operate, be sure you understand how EVERY switch works: change a fuse, run the AC.
Make sure that ALL systems are GO. ASK the dealer if you aren't 100% sure about something you notice. You paid him to do that, remember.
In other words, look for "deficiencies
". You WILL have them, just like a new house has them, since there are a LOT of systems and nobody is perfect.
So next you MAKE A WRITTEN LIST OF ALL OF THEM
and hand in a copy
of it to the dealer the next morning, and either stay there until he has them all done, or get his written response to your list as to when everything will be in stock so as to have the repairs done to your satisfaction.
After all HOW many trips to his place do YOU want to make to his place?
Then go camping, and enjoy...!
