Magnum Motorhomes, motorhome and caravan supplies in Grimsby

Magnum Motorhomes & Caravan Supplies Ltd is a family-run business with over 70 years of accumulated experience in the sector. It was founded by Ken Carter, who after years building caravans for Abbey Caravans began manufacturing his own motorhomes and selling surplus caravan parts. Since then, the company has built all kinds of conversions, from coachbuilt vehicles to panel vans, race units and even a 52-seat coach.

Current activity: supply shop and warehouse

In recent years, Magnum Motorhomes has become known as one of the largest warehouses of building materials and accessories for caravans and motorhomes, with a large warehouse and shop in Grimsby. The company supplies both the trade and the general public and enthusiasts who carry out their own conversions.
