The title of this thread should be "you need a spare if you travel in areas where you may experience loss in cell signal, or remote areas that may not have easy access to RSA and a place that can bring you one".
A lot of RV'ers - including us - don't fall into that category and have gotten along just fine without a spare - despite having a flat. I would go so far as to bet that a lot of folks that carry spares never use them. I've owned my pickup for 13 years, never used the spare.
I understand self reliance If you want to carry one and feel the need, awesome and good for you. But a lot of folks simply do not "need" to carry a spare.
