I have a new swift sundance 630l. I wanted to know if it is best to turn the cabin power off while driving or whether it is fine to keep it on as i want to charge the fridge while travelling. I also wondered if anyone knew if it was easy to disable the passenger seat airbag so i can put a child seat in the front. Does anyone else have problems changing the gas bottles? The design of the gas locker means it is difficult to get purchase on the bottles and the securing straps are very cumbersome.
