The private message I'd sent was about certain aspects of this Delta.
It appears that they have not constructed the best advert possible for the Dandy that they have for sale.
The Delta is uninsulated but it does have an underfloor heater. A previous owner was an electrician and wired the electrical fittings. These look to be better than many that I have seen. The co-ax sockets are an often used modification for 12v as the plugs are more readily available and less fragile than the original 12V plugs.
I've still not worked out what the black box is to the RHS of the picture. A second or dedicated cold box transformer? Nor if the battery charger is just acting as a 12v power source or if there is a battery for 12v when not on EHU. Apparently there are awning lights as well as the low level light pictured.
I'm not promoting nor recommending this Dandy we don't do that. We always advise anyone to have a thorough inspection before buying any Dandy. It's just that while I'm slightly sad that the family_of_3 have not advertised this as well as they might, it is such a joy to read an undersold ad. Most of the time I'm tacking notes on to adverts saying, "Watch out for X", "I would ask about Y" or "They have not mentioned Z".
If you want further evidence of ownership and corroboration that they are not selling on just because they bought a pup why not look through the threads that they have posted on? [You must be registered and logged in to see this link.]
I do wish them the best of luck selling this.
