Hi, we've got a 530 GT 2015 - chose the fixed bed model, which is surprisingly comfy. We opted for the hot water supply, sprung cushions, spare wheel and motor mover. We don't have an awning, decided on a Caravan Store from Fiamma, it's perfect for both sunny and wet conditions, it's light and easy to put up.
We opted for the Truma gas heater - but bought compact oil filled radiator, which I feel, distributes the heat better.
If your buying the 2016 model you might get some of the equipment I quote as standard.
Good luck with your choices.
