The Truma Duo valve with crash protection

I have two regular propane gas bottles in my gas locker and it's becoming a regular pain having to remove the connected bottle to see how full it is.

The four-year-old is fussy about here ice cream and I don't want warm beer when were away from EHU. I don't fancy waking up in the morning and having to change a gas bottle when its horrible and dark outside and the heating won't come on.

I've just come across this and am a bit concerned about some of the things I've read about them like the need for expensive filters and oil from various sources fouling the regulator. Are there any alternatives ?

Also, is the crash protection sensor prone to being over-sensitive and switching the gas off when you over a bump in the road ?

Am I assuming correctly that the gas hoses I would need to fit my two Spanish Cepsa refillable gas bottles are the regular ones that I use which are connected to the gas tap

Thank you for your help in advance.

Well advisable to fit the filters to the Truma Duo, they have come down a lot in price Autogas 2000 sell them for £40 each the TrumaDuo you can get for under £200. You will also need anti-rupture pigtails to connect to your bottles if you want to drive with the gas on, about £35 each.
Never know the crash sensor go off even on the roughest roads, had them on the last 2 vans.

I've used over 1500 ltrs of LPG since having Alugas fitted in 2016... ( Keep a record)..
No filters, no hiccups with crash sensor...
No issues with fridge 👍 I'm full time and mostly on solar and LPG... as opposed to EHU

Our crash sensor shuts off on rough roads, all the time, real pain!

Perhaps it's the fitting "type"....
Mine is fitted to the bulk head

And I was informed by Autogas... 5g impact to set it off...

I think all the crash protection regulators are bulkhead mounted. We have been down some horrendous Belgium roads never had a problem.
I think you's right... But there are two types..
Horiz... And vert... 😎

Ours is vertical, never trips in France, mainly on our roads in Scotland.

Well that's put me off ! Nice idea though but if it has potential issues with bad road surfaces it's a no-no. Thanks very much for your replies
