Hello and welcome!
Sounds like a big move and I'm sure you want to be as ready as you can.
We can help you along the way!
First, I would highly suggest to get a Full member upgrade. It's only 5 bucks and gives you access to the members area where we have over 200 manuals, diagrams, and other tech info for your P30 chassis and all yout appliances, furnace, water heater, air conditioner and a lot more.
Right at the top of the list of manuals and diagrams is the P30 series.
