Thats great, thank you. I will have a look.£2200 in total. £1950 for Rib and £250 for fitting. It has isofix, crash tested and bolted to the chassis which the Rolla bed doesn't have any of those features.
They were the cheapest I found as in avg it was £2900 but they bulk buy so can offer the discount.
Space wise, you get more under the seats at the back and more functionality with how it can be set up in different recliner positions and creating a large parcel shelf etc.
You tube has videos demonstrating it.
