Yes, you can, but it may be a bit of a pain when pulling out the fridge.
We chose AS over KK mostly for the fact that the fridge does swing back against the camper, and to be honest, we have never had an issue with cooking smells going up into the bed area. The other reason was that we have a 60l Trailblaza fridge, and not only did it not fit it the KK, they did not recommend amending to be able to fit due to the drawbar weight. We didn't want to buy a smaller fridge, and AS amended our fridge box to suit. We think it is much better with a flat nose now as it is easier to sit things on top, eg when getting things out of the pantry and fridge.
Both campers are very well made and have great attention to detail, it will be the little things that sell either one for you in the end. We couldn't be happier with our decision, I'm sure you will be too when you work out all your personal pros and cons.
