Here is the brand new double seat swivel base designed by the Customshop team (Community Registered Design 001382212-0001). We have been manufacturing and supplying camper components to the trade and public for over 15 years now. The Dodge Promaster camper van / motorhome double seat swivel base is the most compact seat base on the market with all locking points hidden away, it has a more streamlined look compared to other bases on the market (raises the seat by 50mm). The locking points work on a unique 1/4 turn 'quick release' system so removing all 4 fixing bolts and rotating the base takes literally seconds! They are manufactured in the UK and made from 4mm laser cut steel, and has passed M1 seat belt anchorage safety tests using a pull test on a specialist test rig to EC Directive 76/115/EEC as amended by 2005/41/EEC which is a standard requirement for most insurance companies when making this type of modification to your camper, and also peace of mind when transporting your friends and family around. The base allows you to rotate the double passenger seat 180 degrees and lock the seat in the reverse position to completely transform the living space of your camper. It also is compatible drivers swivels / arm rests and has no rattles.! Fits all RHD Dodge Promaster models from 2006 onwards and fixes directly to the existing floor mounts so no drilling required, installation takes approximately 60 mins from start to completion. Comes with step by step fitting instructions.
