Detailed Comparison

Shopping for an RV and torn between the 2024 Tiffin Allegro Bus 37AP and the 2024 Tiffin Phaeton 37BH? We've put together a detailed spec comparison to help you decide.

The Tiffin Allegro Bus 37AP measures 34.5 ft in length at 26,200 lbs, compared to the Tiffin Phaeton 37BH's 44.5 ft and 26,500 lbs. GVWR ratings sit at 30,800 lbs and 31,400 lbs respectively.

Capacity-wise, expect to sleep 8 in the Tiffin Allegro Bus 37AP versus 8 in the Tiffin Phaeton 37BH. With 2 and 3 slide-outs respectively, the parked floor plans differ significantly.

Tank capacities are a key off-grid consideration. The Tiffin Allegro Bus 37AP carries 97 gal of fresh water, 42 gal gray, and 40 gal black. The Tiffin Phaeton 37BH offers 107 gal fresh, 56 gal gray, and 46 gal black. The Tiffin Phaeton 37BH has the edge for extended dry camping.

Budget-wise, the Tiffin Allegro Bus 37AP is listed at $345,000 compared to $491,000 for the Tiffin Phaeton 37BH. The $146,000 difference could cover upgrades, accessories, or several seasons of camping.

For family camping trips, the larger floor plan and additional berths make a real difference. For boondocking, the model with superior solar and battery setup will keep you comfortable off the grid longer. If you're going full-time, the larger tanks and more robust build quality matter enormously.

Take these specs as a starting point, then go see them in person — there's no substitute for stepping inside.
