External electric socket

Yes i have one and every time i park the Motorhome i plug it in and that keeps the fridge cool and sometimes especially in winter leave the charger switched on,in brighter weather i let the solar panel do the work.

I have, helps when stocking up the fridge the day prior to leaving on a trip, or charging the batteries if required.

Allan it's handy to have. I fitted an external weatherproof box with double socket in it which is switchable from inside the house.

Same here! Got an electrician to fit a blue outdoor 16A on the end of the house, a simple job he just drilled the wall and connected it to a bedroom socket, only problem he wired it reverse polarity. Only discovered that lately, we have been using it for the last 3 or 4 years with no problem.

We live in a bungalow and about 10 years ago I got an electrician to put a light into the attic. When he was at the job, he also put a double socket in as well. About 3 years ago I got fed up unreeling leads to plug in the caravan through open windows, so I mounted a 16 amp wall socket about 12 inches under the soffit, drill a hole in the soffit and ran in a 2.5 mm cable and fitted a 13 amp plug on the end and plugged into the attic socket. I chopped about 4 metres off the caravan hook up cable and fitted a new socket and plug. The whole lot runs through the breaker that the electrician fitted into the fuse board for the attic. If my socket or the MH electrics balls up, the whole house won't be knocked out.
Caravan is replaced by a MH now. We plug it in about 24 hours before we leave, mainly to get the fridge operation properly.

Just use the shortest lead .best to have one just the length you need .
No coiled up .

Yea and have the MH lead pluged via a timer.Once a week it comes on for an hour to trickle feed the leisure battery. Not good to leave on constantly as charger will draw more than putting in... Currently looking into a solar setup for roof.
