Has anybody fitted their own LPG tank? Is it difficult to do as DIY? Does anybody know what the largest size you can fit on a Renault Master chassis? I am looking at the MTH gas tank I fitted a Gasgow bottle on my last van but like the idea of freeing a locker & having the tank fixed on the chassis. At the moment I have been told by a dealer that the biggest size I can fit on a renault is only 20 litres:Sad: was hoping for something a bit bigger.
