Unless mistaken, my wife and I saw this pull-trailer promoting GoCamp, which rents camper vans, parked on Florida Street here in University Heights. I perused the company’s website: Including duplicates, 46 vehicles are available from San Diego to the destination of your choice.
Based on interior—exterior, not so much—I rather fancy Van Luca: Mercedes-Benz Sprinter or Gia, which “is a 2009 Ford Econoline 150 Chariot hi-top conversion”. They are available for $179 and $145 per night, respectively. Neither can be driven one-way; got to bring them back. The Benz burns diesel, which is something of a liability because of high costs; the Ford is a gas-guzzler.
