The 2020 Auto-Trail Frontier Comanche Highline is a premium tag-axle motorhome designed for long-distance touring and luxury comfort. It is typically built on a Fiat Ducato chassis with a 180bhp engine and automatic transmission, measuring approximately 8.78m in length. The Highline variant offers an overcab bed, allowing for increased berth capacity (often up to 6 berths, depending on configuration) compared to the Lo-Line model.
