Thanks for the advice everyone.
I have a Nissan Kubistar and have seen an advert from Pure Freedom for a DIY Kit for about £650 not sure if thats any good but price seems cheap.
Picked up info on here for leaflets at a good price also sign writing from EBay.
This forum has saved me so much time in making wasted money mistakes.
If I get a DIY kit what is the best way to get it heated without setting fire to the van.
I have a garage with a tap could i get something static which i could fill up over night then all I have to do is fill up my container in the van for a days work.
