Solar connections on Intent 26m

[mdntblu]

I was looking at the Winnebago Intent webpage - https://www.winnebago.com/models/pro...fications=true

If you drill down to Electrical System it says the following:
Solar panel/battery charger prep kit, with three-way plug-ready port located on roof and a single port located in exterior bay

I have an Intent 26m (2018) and was wondering where this port in exterior bay is located. I didn't see it anywhere when I was looking.

For those that have a 2018 Intent have you done solar? If so what cost was it?
