Yes there is a difference. Our previous 5er was a Komfort 291fsg, our current is a Arctic Fox 27-5L 5er. In the Komfort the fridge is on the back wall, our Arctic Fox is on the side, near the wheels, thus potentially less bounce than on the back wall. I say potentially as only once did we have a jumbled mess in the Komfort fridge. We were headed to Astoria and taking 217 through Portland. They were resurfacing the road and had ground down the asphalt then built a short ramp on each bridge. It was like an elongated speed bump. When we got to our destination, carefully opening the door we were unable to until we unloaded the jigsaw puzzle one thing at a time. But nothing was broke or popped open.
