Winter camping places higher demands on a motorhome than summer travel. Key factors include good insulation, a powerful heating system and frost protection for water lines and the waste tank. Among motorhome types, those with a well-insulated body, a driver's cab separated from the living area and a heated double floor have an advantage. Semi-integrated motorhomes are considered a balanced compromise, alcove models suit families but the alcove can be cold, fully integrated models lose heat through the large windscreen, and camper vans, despite their compact size, have many thermal bridges. For extended stays in severe frost, classic coachbuilt motorhomes with a heated double floor are usually preferable.
