Am planning to fit a 12V socket in the locker beside the freshwater tank in my MH (Burstner Ixeo) to power a submersible pump for filling the tank from the Aquaroll (currently use a long lead from the 12V socket in the dash). The locker is conveniently close to the location of the leisure batteries and I want to run the pump from them to make it independent of the ignition. If it was my old Land Rover, I'd just run a cable from the positive terminal of the battery (with an in-line fuse close to the battery) to the device and find a suitable point on the chassis for an earth. However, I'm new to MH and given that the MH has two leisure batteries I'm unclear if it would be OK to take the positive from one of them or if I'd need to find a positive somewhere downstream of the two batteries. Any thoughts would be most welcome! Thanks in advance.

As you have a Burstner I assume you have an Elektroblock, normally the are few spare positions you can connect to on the EBL, some will be switched by the control panel some will be permantly live. Have a look at the EBL manual, the pins you need to connect are "Mate 'N Lock".

I fitted a 12v outlet adjacent to the water tank in my Burstner last year, I found a cable run in a small panel below the dining table which had a multi connector socket with 12 v supplies, so bought a plug and soldered it up , similar to the attached, took it bit of working out the size and type, job done.

If like you say the battery is close I would just run a twin cable to either one of the batteries with a fuse inline. Only going to take a couple of amps at best and won't be running very long.
I carry a 12v bike / alarm battery and clip the pump onto that as the water input is right in the centre of the nearside wall and I'm to lazy to fit a socket or run a long cable šŸ˜šŸ‘
