The wife and I had the same dilemma. For us, we had decided on the Sterling Elite 650 at the time and almost put a deposit down at the NEC. What we had to compromise on as you usually have to...was for us the smaller fridge. However at the NEC we were offered significant discounts on both with almost 5k off list price. We walked past the Lunar stand and happened to stumble across the new Delta RI. It's the same mid wash layout but with a rear transverse fixed bed meaning you still get the space to the under bed storage from the outside rather than having to bring your bits in through the van. As always there are other things to consider and compromise on. The elite has a fantastic interior and very modern. The coachman is more traditional and similar to the delta RI. We managed to bag a Delta RI for £20k brand new Jan 2016 build with a power touch mover fitted too. I've had Baileys and Sterling caravans and I'd say the build quality of the interior is similar if not better than I've had from my previous manufacturers of 2014/15 build years. If the delta isn't something you've looked at, I'd go with the Elite.
