Chassis Context

The 2025 Airstream Interstate Atlas is built on the VS30 Sprinter chassis — the same generation that introduced MBUX infotainment, advanced ADAS (Active Brake Assist, Attention Assist, Crosswind Assist, Lane Keeping, Blind Spot, Rear Cross-Traffic), and the hang-on AWD system that replaced the earlier transfer case. The 2025 can have either the OM642 3.0L V6 or the OM654 2.0L inline-4 biturbo diesel. By 2025, Mercedes had issued multiple software updates for early MBUX lockups and camera-calibration drift — check for pending updates at any dealer visit. A critical VS30-specific note for RV owners: the smart alternator intentionally drops to 12.3–12.6V during highway cruise to save fuel, so voltage-sensing relays do NOT reliably charge coach batteries — a DC-DC charger is required.
