Underslung or bottles

[Pablotti]

I had refillable Gas-it on the previous motorhome. I had decided to give Gaslow a try on the new one, but just realised an underslung tank might be viable.

My thinking is, larger capacity so fewer fill ups, and the existing gas locker can be used for additional storage. We’ve got the payload too.

What are your views?

Underslung, no quibbles. Low centre of gravity, space, outside high pressure in case of fault. Body mount fill point many think is for the engine, so I get filled up before I get asked.

We have 2 x 11kg cylinders so roughly have 42 litres of gas on board when they're maxed out (at 80%), but the largest tank you can fit on many MHs is 28 litre so if you're used to 2 cylinders you could find you have less gas than before, not more so check out what will fit first as that will likely influence your decision.

Excellent point. I was mixing up kg and litres.

I fitted a 38ltr underslung LPG tank under our Peugeot Boxer-based MH essentially for our foreign travels and to gain locker space.
I also fit a Mopeka bluetooth gas level sensor to our tank, and that gives a very accurate reading for the gas level in the tank.

I reckon my 2 x 14 kg Alugas bottles hold over 50 litres.

The question is though, will 28 litres be enough for you. If it is then I would suggest the underslung tank is much the better option. I bought my moho in June (underslung tank). We still have half of it left so bottles wouldn't really give us any advantage.

What he said. All of it.

As has already been said it’s almost certain that you will get a greater capacity in your gas locker than an underslung LPG tank, most modern vans have limited ground clearance and very little space for large underslung LPG tanks.
We fit hundreds of LPG tanks a year as many of our customers have both underslung LPG and refillable cylinders .
Some vans will take the 14kg Alugas cylinders but they have been in short supply and expensive compared to Gaslow.
Remember you need 200mm minimum ground clearance for an LPG tank as we see far too many that are installed lower

By my reconning you'll have just under 54 litres.

Just multiply Kg x 1.96.

54.88 litres in this example.

Underslung may seem a good idea but there's not always enough space down there to put a large tank.

That's why we went for cylinders. Fitting a tank would also have been a lot more expensive.

OoOOOOOooooOooOo .... picky or what!

Yep. I am lucky that previous owners fitted a 70 litre tank giving 56 litres useable capacity. The Truma regulator is still in the “gas locker” so all I need is a pigtail or two if push comes to shove
