Campervan Conversion Costs and Materials. How much does it cost to convert a Vauxhall Vivaro LWB from a panel van to a fabulous campervan?

I hope it will be a good guide if you are looking at doing a campervan conversion of your own. The video covers the whole budget for this camper van conversion.
