Roof Zone Load Map -- Really?

Can this Roof Zone Load Map be for real?

North Dakota has the same requirements as Florida? Really? So I can buy a home in Dallas and place in South Dakota? That seems crazy.

For California MHPs, I know this isn’t true. The snow load varies by county and elevation.

Don’t forget the Climate Zones. It would interfere with Dallas to South Dakota. Dallas, if I remember right is 1a and South Dakota is 3. That would require more insulation in roof, floor, and sidewalls with maybe some differences on windows, et al.

I love the fact that Erie, PA and Miami FL are rated the same.
