Firstly I needed some donor parts, to achieve this in one hit I thought it best to buy an insurance write off from a salvage place in Southend on Sea, here you can usually find one or two suitable donor vans. salvagecaravans.com
The interior components was what I needed, 12V & 240V electrical system, plumbing, water heater, cooker, hob, fridge etc.
The shower room was going to be one of the trickier tasks to complete.
