This is just another great gimmick to part motorcaravanners from their cash - I love walking around motorhome shows and looking at all the useless and expensive gimmicks that seem to be invented with that in mind rather than actually being useful.
Sure nitrogen is more stable than regular air, but if you do need to top up for whatever reason you arn't going to wait to find a nitrogen suppplied air machine at the next garage.
I like normal air in my tyres and if they go down a bit I can usually find some normal air to top it up either free or at a small cost .

waste of time and money.. and like a few have said..you cant top it up with normal air so wots the point??

And if you check your tyres regularly, and top them up by a wee bit as required eventually you will increase the concentration of nitrogen as the O2 dissipates....
