The Allegro Red line has earned a reputation as one of the best values in diesel pushers, and the 37 BA makes a strong case for that title, a Cummins L9 pushing 380 horsepower and 1,150 lb-ft of torque moves this coach with serious authority, backed by Freightliner's XCM chassis with custom-tuned Sachs shocks and full air brakes. Inside, the single full-bath layout centers around a well-appointed living space with Spyder multiplex controls managing everything from touchscreens throughout the coach to the 8kW Onan diesel generator with auto-gen start. Optional hydronic heating means radiant warmth underfoot, and an available washer/dryer keeps longer trips genuinely self-sufficient. Tiffin's build quality shows in the details. VALTO all-composite sidewalls, a one-piece gel-coat roof cap, and steel basement construction, and their customer service reputation gives buyers added confidence in the relationship after the sale.
