 For one, the tent's frame is now external, with the canvas supported by elastic loops and plastic hooks, somewhat like a shower curtain.Instead of a single opening front panel, there is a zippered screen door in the middle of the front (side away from the bus) with a small awning flap that can be lowered for wind and rain protection.This tent also features a waterproof floor, and the attachment method on the vehicle side results in a securely closable shelter (i.e., no more gap below the bus floor).
