2026 Alliance RV Paradigm 388SP

The 388SP is a rear-living luxury fifth wheel that punches well above its class, with standard features that most rigs charge extra for. Including 400 watts of solar, 6-point hydraulic leveling, TCS touring coil suspension, and a Helux coil spring pin box that owners consistently call the best ride they've ever had towing. Inside, the King bed sits under a residential-style headboard with a window above it, flanked by proper nightstands and reading lights, while a fireplace with a 5,100 BTU heater anchors the living space. No carpet anywhere keeps cleanup simple, and solid surface counters, undermount sinks, and a one-piece fiberglass shower give the bathroom a genuinely residential feel. For full-timers who want to go deeper off-grid, the optional Victron-based solar and lithium package. Up to 1,200 watts of panels, a 3,000-watt inverter, and 400 amp-hours of lithium. Turns this into a serious boondocking rig.
