The Aptera could lend itself to a great tailgating vehicle too. I will write separately on some ideas starting with
Outdoor Audio Speakers
Although conventional interior speakers can double for outdoor speakers. My Honda Ridgeline has rugged outdoor bed speakers. They simply have exciters behind the resin bed side panels and the resin panels serve as the cones of a speakers. The Ridgeline’s audio is simply switched to bed speakers. They designed an anti-annoyance feature to only operate if you decide to drive up to ten miles/ hr....to prevent people from blasting while driving in general.
Aptera’s unique resin may have some similar possibilities for this alternative speaker technology too.
Love the camping option but these ideas add to the functionality of the feature
