Promobil magazine reviewed 12 fully integrated motorhomes (vollintegrierte Wohnmobile) as entry-level luxury models. All are built on Fiat Ducatoⓘ or Mercedes Sprinter chassis, up to 7.5 m long, with base prices from €100,000 to €145,000. A key issue is curb weight: most are registered as 3.5-ton vehicles, but due to heavy construction (large windshield, double floor) payload is limited. Upgrading to 4.4–4.5 t GVWR is recommended for practical use.
