I need a new project and I was thinking about installing my spare ARB compressor with an air tank in the rear somewhere to be used for airing up tyres. I know a number of you have already done this so I'm after some advise .....

Is it worth it, is it an advantage, or am I better off sticking with my Thumper when needed? If the answer is yes, what size air tank do you recommend to make it viable, bearing it mind the available spaces inside or under my y61?

Thanks guys
