The Keystone Passport SL 178RD keeps things simple: a compact, easy-towing travel trailer with a full bath packed into a layout that sleeps four. The Passport SL line has earned a following for its approachable floorplans and light weight, which opens it up to a wider range of tow vehicles. That said, owners on RVInsider rate overall quality at 3.7 out of 5, and the line does carry a reputation for inconsistent build quality and trim work, so a thorough pre-delivery inspection is worthwhile. For buyers who prioritize towability and a straightforward layout over premium finishes, the Keystone Passport SL 178RD delivers solid value at an entry-level price point.
