My van has a100AH AGM battery and I also have a 105AH AGM battery that I would like to install in my van. What is the downside ( if any) to connecting and charging them together.

Hi Could some one please explain how these absorption fridges work in relation to the thermistor. Thetford N3185 On 240 v mine draws around 1.4 amps, so rated at 300 w this seems ok but it never seems to change or cut out. As the thyristor gets cools shouldn't the current decrease in proportion to temp se...

Am thinking about the above, and in hindsight, I should have done it B4 Nov. 2023 and the introduction of AS3000, reading the thread below it would seem that not only do I change over 2x 120amp AGMs for 1 x 135Amp Lithium, I will also need to change over the cabling to solar approved cables from my solar pa...

Thinking of getting a 12 volt pump to transfer water from 10 & 20 litre containers into van tank. Getting a bit hard to hold them up and pour into funnel.

Hi all. Wondered if anyone can recommend a good quiet water pump. There are so many on the market. Would prefer a recommendation. Thanks Carol

My skill at reversing a van are not the best, despite practice. A suggested solution is to mount a tow ball/DO35 on the front of my Dmax. Im searching now for examples of such an arrangement. Anyone here know of when, where, or how its been done?

Good afternoon everyone i forgot to ask, in my water pump post of yesterday, about CPAP machines whilst caravanning. Any recommendations? The Sleep centre advised that the portable machines are noisier than the bigger machines. I also wondered about battery draw as I mostly camp offgrid. Much ap...

Just replaced electric heating element in my 2012 year model Truma b14 hot water unit with an 850watt element and after 1hour 15minutes the water is barely warm. I would expect that it should be quite a bit hotter than that as the old element would heat it up in about 45 minutes. Is there anything that I ma...

Have a C4 Thetford Bench Style Cassette Toilet in our Sprinter Campervan.

Had a very slow tyre leak over the past year losing about 3-5psi each month. Did not worry me too much and just inflated regularly as required. I knew I would have to do something about it one day when I had more time. That time came last week. So, I removed the wheel from the car and inspected the tyre. Sure e...

I am getting some backflow from my sink to my shower, can anyone suggest a type of non return valve that would be suitable. As there is no pressure then a spring loaded type wouldn't work, I was thinking a swing check valve may do the job. All the connections are 25mm flex tube. Has anyone fitted one or solv...
