Having just saved 3KG by moving to a DKN grey waste container from Aquaroll I'm wanting to take advantage of the weight benefit of moving to a Flo-Gas Gas Light bottle from a 6 KG Flo Gas Propane Bottle (which should save me ~5KG Tare weight ).

Two questions come to mind:

1 The bottle diameter looks tight for our 2019 540 Troll - has anyone made the move and managed to fit it in the gas locker successfully.

2. What changes do I need to make to the connection to the Van's regulator

Many thanks

Thanks Colin
That's most kind of you to supply the links as well. It gives me the confidence to progress now.
This will be the last job of the year for me having just replaced the Truma boiler.

2019 van and you’ve had to replace the boiler?!?

Steve.

I'm intrigued why a boiler would need replacing after just 5 years too? However if you're scrabbling for weight allowance have you allowed for the fact that the weight through the hitch (noseweight) is borne by the car, not by the caravan axle.

Thats an interesting point Andy. But isn't the MTPLM also based on the the load the structure of the caravan can take as well?

The boiler failed due to a leak at the lip of the vessel and not viable to weld repair. Yes I'd expect it to last longer than that. The original installation had not fixed the boiler to the floor via the ply base plate particularly well allied to a possible weak production weld at the lip was the probably cause of the failure.

I had the option to replace the vessel only for about £260 and frankly the option to pay the extra and get a fully warranted new boiler with the associated peace of mind drove me to replace the whole boiler. The replacement was an easy job. I'll sell the old boiler for spares later.

As regards the weight there is a limit on the towball at about 75kg with the our car. With two electric bikes and other bits and bobs in the gas locker there is no added value in driving up and down the country with an 8Kg steel cylinder when the 3.4 Kg Gas light does the job. we are using about 2 kg of gas a year. Hence the case for light weighting was easily made.

The more trips we take the more we realise how much stuff was not being used. In fact the cabinet between the beds just gets in the way so that has been left at home for the past year with no detriment. Less is more!

Good points and well made Colin.
We use a Milenco nose weight gauge to get the numbers and yes the laws of levers does deliver the answer when you shift the mass behind the axel or into the car. I'm driven as much by not carrying "excess baggage" as a principal. By the way the new cylinder fits brilliantly into the gas locker and the new pig tail and adapter arrived today.

Thanks again for your advice.

Thanks Colin
I love this,
In a similar vein I took an inventory of everything in our house and have used that to declutter out lives.
Control is everything!
