Two Categories, One Name: Understanding What “Fold-Out” Means“Fold-out cabin” gets used for two completely different things, and nobody in the space bothers to separate them. Compare that against a Tesla Model Y with the factory tow package, which is rated for 3,500 pounds of trailer weight. Tow rating and tongue weight are two different specs measuring two different forces, and the Model Y’s max tongue weight is 350 pounds. The number that actually stops you is the one nobody prints in bold, and it’s worth asking for by name before any deposit changes hands. That’s a real, buildable number, and it’s the one every off-grid buyer actually needs before signing anything.
