We have been told to get a long cable to plug in our Motorhome to the outdoor socket to keep leisure battery topped up when MH is not being used. (It seems that the alarm will drain the battery over winter??)

We have bought a mains coupler to plug into the MH - do we need blue 1.5 mm cable or yellow 2.5mm. I have read that one is 16amp and the other is 25amp. 
Can’t seem to get hold of one in our local camping stores.

You mention keeping the cab battery  charged - is this something we should know about?  MH will be stored at home ver winter. Just thought we would need to keep the leisure battery charged.

if you left your car for weeks on end without use it's a good chance the battery would go flat on it .... same with your motorhome. 🙂

It would probably be handy if you mentioned the make and model of your motorhome as it might be easier to identify what, if any, alternative arrangements need to be made. Even if you have a solar panel you need to check whether a charge is going to both batteries or just the leisure battery. Some makes only charge the leisure battery  and then even within brands there can be differences. The only thing we know for certain is that the cab battery is charged when the engine is running! Even if the charger does not provide a charge to the cab battery there are simple solutions. Something like a Battery Master will push any excess charge to the leisure battery through to the cab battery keeping both fully charged.

Do you not have a cable for connecting your van to electric if you are using EHU on a site?  If so, with appropriate connector (weather proofed if necessary) you can use that cable to connect to a home socket.

I have spare hook up cable that I have shortened  that we use to plug our caravan at home rather than having a very long cable spread around the drive or forming any coils in the lead plus we can leave the long lead in the van and not have to coil it up and stow it away before setting off or indeed leave it at homeyell

Coil the cable up, turn everything possible on to draw current, warms the cable up makes it easier to handle, job done. After all you are paying for the hook up, plus a surcharge on a CAMC site.tongue-out

OP use as short a length of cable as you need, clip it to your house wall, plug into a timer to charge for a couple of hours a day. Our caravan is plugged into an old EHU cable cut short, clipped below damp proof course around the house external wall, plugged into a timer in the garage on a protected circuit to only come on when our solar PV system is generating. You don't want to leave it on 24/7 in case you boil the battery. You could add a battery charger on the vehicle battery from the MH 240v supply that then only charges as and when, or a battery master type device that maintains charge level.

My EHU cable is black rubber - and thicker than a 'normal' orange, plastic coated EHU lead.  It was supplied by Knaus with the van and is much much easier to coil up than the orange one.

I do worry, though, that it's not as visible when in use and always make a point of pointing it out to site owners before grass cutting starts.
