Hi, our shelves have rusted, however, they do stay in place. The problem we had was we couldn't get the b****y thing to light on gas. On one occasion it took 12 hours, going back to it time after time after time. Told the dealer and all of a sudden it works.
My biggest worry is that when the gas runs out overnight the ignition is firing away all night trying to ignite gas and then one has a flat/low battery. We have asked repeatedly for a switch to turn off the electric (12v) supply to the fridge, but it cannot be done. Elelctrolux, or whatever their name is now, can do it why not Thetford.
As stated above, they should stick to toilets.
I liked their adverts in the two club magazines.
