This list is extensive so warn your dealer if you are going to use it. Average PDI for 5th wheel is 2 hours. This list will take WAY longer than 2 hours to go through. I did not use this list. I simply went room by room and tried everything out that I could.
Good idea to hook up water and electricity at PDI and try out all functions. Then try out all functions that should work on battery only. Be advised that some applicances that run on 120VAC wont run on 12 volt battery. DVD, TV, microwave, air conditioner, etc. Ask your dealer.
