Do you use Levelling Ramps very often ?

Last year, we had nearly 60 nights away in the MH and didn't use our levelling ramps at all, mainly because we used hard standings most of the time.

We're also probably lucky as the length of our van (8 metres) means there's a good distance between the front and rear axle, so any slight slope towards the front is hardly noticeable.  The  drain for our shower tray is also towards the front, so the water runs away quite easily. 

Some people will suggest the fridge won't work properly if it isn't level but again, this hasn't been our experience and it has been tested in varying conditions from -14 to +30 degrees C.
