What is a Coachbuilt Motorhome?

A coachbuilt motorhome is a vehicle where a separate habitation body has been constructed and bonded onto a commercial vehicle chassis cab, typically a Fiat Ducato. Unlike panel van conversions, coachbuilts feature purpose-built sandwich-panel walls, a distinctive overcab section, and significantly more internal living space.
