I already have a Top Box but I need a little more space so I am looking to remove the rear seats. The car is the Fabia Monte Carlo Estate 1L 2019 I have had the Yeti and this presented no problem, but the Monte seats don't fold down flat. I have camping gear that fitted perfectly but thanks to Covid I need a separate shower tent and a bigger porta potti! hence the need to remove the rear seat or perhaps just the backs. I'm getting on a bit so talk slowly
