Has anybody had experiance with BP Lite Gas. I considered purchasing a bottle today but was asked what bulkhead regulator was fitted to my van.The person I spoke to said the Truma one fitted to the van would not work and I would have to change it for a BP one which works with both Calor and BP which is strange as I thought the gas was a BP and Truma cooperative. I was also informed that the level of gas was not clearly visable which was my incentive to purchase BP gas.
