Some good wisdom there Heinz, thanks. I particularly like
"I would definitely try it out without ATBs, at least on a trial basis, to see how it drives before you spend any money on any parts. You might be positively impressed by the new driving experience". So I'm going to put the removed rear shelf, carpet, and trim pieces back in place, and go out for a drive "ATB-less".
Also, I may have overstated the weight aspect. I checked: 1.1kg for my detached one. That's the same as say a bottle of wine, a cricket bat, a pair of shoes, or 1.5 litres of petrol -- all commonly-found items in a Mog.....
