How many tanks can I connect together
You can connect any number of GAS IT gas tanks together from 1 fill point, or 2 fill points if you want to so you can fill them from either side of a big motorhome or trailer.
The sizes of the GAS IT tanks can also be different so you could have for example, 1 x 25 ltr GAS IT tank and 1 x 50 Ltr GAS IT tank, and because each GAS IT tank is fitted with its own automatic 80% shutoff valve, gas will only be put in the tank(s) that needed it refilling.
Its also worth noting that you can also technically connect as many GAS IT refillable bottles to GAS IT refillable tanks via 1 fill point as well.
Before you go fitting several gas tanks do take in to consideration the weight of the tank(s) when filled with LPG and your vehicles spare carrying capacity.
