Detailed Comparison

Comparing the 2025 Thor Aria 3901 to the 2024 Fleetwood Flair 32S reveals some interesting trade-offs that could influence your buying decision.

Starting with size, the Thor Aria 3901 measures 35.0 ft long and tips the scales at 16,800 lbs dry weight. The Fleetwood Flair 32S comes in at 27.0 ft with a dry weight of 24,000 lbs. That gives the Thor Aria 3901 roughly 8.0 extra feet of length.

Capacity-wise, expect to sleep 5 in the Thor Aria 3901 versus 8 in the Fleetwood Flair 32S. With 1 and 4 slide-outs respectively, the parked floor plans differ significantly.

Tank capacities are a key off-grid consideration. The Thor Aria 3901 carries 91 gal of fresh water, 41 gal gray, and 37 gal black. The Fleetwood Flair 32S offers 119 gal fresh, 65 gal gray, and 40 gal black. The Fleetwood Flair 32S has the edge for extended dry camping.

Budget-wise, the Fleetwood Flair 32S is listed at $312,000 compared to $313,000 for the Thor Aria 3901.

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.

Ultimately, both rigs have their merits — test drive each one and see which floor plan speaks to your lifestyle.
