Congrats Bill on your new Newmar to you.
There is a PDI list up in the New Rig Showoff forum that will give you some idea as to what to look for.
The furnace will seem loud at first but you will get use to it, its doing its job just don't try to insulate around it it needs the space to draw in cool air from coach interior.
We will be here to help with any questions.
Have a good PDI and look over and under your chassis and fluid containers for chassis.
Oh yes almost forgot when you want some "Karma" just let me know.
