My Expert Opinion On The Offer
Priced at $699,995, this 2026 Allegro Bus 45 OPP represents a staggering $226,000 reduction from its initial $925,998 MSRP. In the realm of ultra luxury Class A diesel pushers, discounts of this magnitude typically signal a highly motivated dealership rather than any inherent flaw with the unit itself. The inclusion of the upgraded Cummins X15 engine is the true differentiator here. Churning out 605 horsepower and a monstrous 1,950 ft-lb of torque, this powerplant elevates the coach, effortlessly managing steep mountain grades even when loaded to its 52,000 pound GVWR or towing a heavy secondary vehicle.

While dropping nearly $700,000 on a depreciating recreational asset remains a monumental financial commitment, the sheer volume of high end standard equipment, from the 10.0 kilowatt Onan generator to the Valid air leveling system, justifies the cost for the right buyer. It places this coach in direct competition with the likes of the Entegra Cornerstone or Newmar Essex, but at a decidedly more accessible price point for this tier. If you are a dedicated full timer or an affluent traveler seeking a turn key, no compromise mobile estate, this heavily discounted unit is a highly compelling, competitively positioned acquisition in today’s high end motorhome market.
