Here's some camping stuff in the Frunk:
That would be:
* 1 Tent (Big Agnus)
* Duffle bag with clothes
* 1 Grill
* 6 bottles of Wine
* 2 BBQ sets
* Handheld Vacuum cleaner
* Toolkit
* Gas
I used to go camping with a Toyota Highlander, and always needed to carry a cargo carrier on the roof, which was generally always full. We didn't economize on what we pack when we switched to the Model S, but all camping supplies now fit easily in it.
So as a rule of thumb - a Model S with Frunk (full frunk, not AWD frunk) is equivalent to a Highlander with a rooftop cargo carrier.
