I agree. with WCamper.
Prior to our current Bailey Senator with Alko wheel carrier we had an Avodale Malvern and a A/D Landranger. Both had the internal, underfloor spare wheel well.. I had to change the wheel on both 'vans, easy peasey. Lovely clean spare wheel which lifted easily out of the storage well. Whe the wheel had been changed the wheel with the puncture dropped easily into the well until the tyre could be repaire.
A couple of years ago at a night halt in France with the Senator we awoke to find a flat nearside tyre. It was a tustle to lift the c'van high enough on the muddy pitch to get the spare wheel out. I hasten to add the wheel carrier was well greased AND I had practised removing the spare wheel when we first got the c'van. After I had changed the alloy wheel for the steel spare as space in the car was at a premium I foolishly tried to get the alloy wheel into the underslung spare wheel rack. It wouldn't fit and I ended up badly scratching the wheel on the securing bolts. Wheel with the puncture had to be squeezed into the car. By this time I looked like a mud wrestler and had to have another shower
before we could get going, delaying our journey even more.
When we got home I had to have alloy wheel refurbished.
As you say not fit for purpose. The Avondale central gas locker was brilliant too. No noseweight problems with those c'vans.
So much for progress.
