OK, so while we were 500 miles away in Scotland, our gas regulator packed up. I spoke to Lee at Timberland at 5.00pm on the Tuesday, he phoned at 8.30am next day to confirm the regulator model, by Friday morning, the regulator was in place and we had gas once more. We were impressed with such fine service and said so in another thread.
Lots of folk on this website complain that members only post about dealers if there is bad news. I am now making the effort to praise good news.
A week later, the boiler packed up!! We were still way up in Scotland. But we had both oil-filled and fan heaters available to make use of the mains-hook-up to which we had access. Water had to be boiled in a kettle, just like proper camping!!
Lee at Timberland contacted Truma. It was decreed that the boiler PCB was at fault. Lee offered to send one for me to fit but I asked for it to be left until we were home.
So, on Monday 23 March, Our Coral was at Timberland to have 4 jobs done... replace a faulty rope light in a locker, replace a double-glazed window unit which had marks inside the unit,

, correct a non-functioning reversing sensor and sort the failed boiler.
I popped in late on Wednesday (25th) and met Lee. The sensor was a loose wire, the light had had been replaced, the window had been swapped and THE NEW BOILER WOULD BE DELIVERED BY TRUMA AND FITTED IN THE MORNING.

I was shocked to hear that.
At 1.00pm on Thursday, Lee phoned to say all the work had been completed and Our Coral was ready for collection.
Because of the positive efforts of Lee at Timberland, AuntieSandra and I were able to enjoy the Newark Show before moving on to Mablethorpe last Monday. So it's a big WELL DONE TO TIMBERLAND!!
