Adding a 3rd AC unit top side?

I know that the Berkshire has a 3 ac/10K generator option available on the build option list.

Question is, is the roof frame built the same on all Berkshire coaches to where if an owner wished to add a 3rd AC unit to the coach aftermarket wise is the roof frame structure already built to support the added AC unit?

I know that it could not be powered by the 8K generator at the same time as the OEM 2 AC units, but it could be powered up while parked with a extra 20amp separate plug and cord.

On a past National Pacifica motorhome we were able to do this by placing the new AC in the opening of a roof vent/fan location. However on this Berkshire this would mean mounting it off center of the roof, more to the driver side of the roof curve directly over the kitchen counter.

Thanks in advance,

2018 Berkshire XL 40B

Call Forest River and ask them. My money is that all roofs are the same and that they can, and may, send you an email with where the frame hole is.

If they cant.... wait till an unexpectedly cold and dewey morning and climb on the roof.... you may see it.
