What sets the 425FO apart is the front office tucked alongside the living room, a real dedicated workspace with a desk, not just a counter with a stool shoehorned in. Up front you also get a 5,200 BTU fireplace, pull-out dinette, and an 18 cu. ft. French door refrigerator with ice maker, while the rear King bed suite stays private and quiet. The Splendide stackable washer and dryer, Fisher & Paykel dishwasher, Truma on-demand hot water heater, and Calcutta solid surface countertops throughout make this feel less like camping and more like relocating your house. The automatic 6-point hydraulic leveling and LCI Road Armour suspension handle the heavy lifting on setup and towing.
