A fresh and flexible feel

Each meticulously-designed floor plan in the Allegro RED brings its own personality, giving you the freedom to pick a setup that fits how you like to travel both far and near.

The 33AA floor plan is the smallest at 35' 2", so it’s a great choice if you need an agile vehicle that can maneuver easily through compact campgrounds. The 33AA also includes four slide-outs, one more than the other layouts, so you can expand your living space whenever you please. 

The largest floor plan, the 38KA, features bunk beds and the largest fridge, which you’ll appreciate if you travel in big groups. The 37BA floor plan measures 38’ 6" and acts as a middle ground between the other two choices. The 2026 Tiffin Allegro RED is also available in two versions: one that uses propane and one that eliminates it. You may opt for the all-electric edition for a quieter, eco-friendly driving experience.
