Now, those size and type of tailors I did see a lot of. Mostly when the whole family went bicycle camping and by those who enjoyed a little luxury during their travels. Usually carried pot pans, kitchen sink and like equipment in those as well as small children and maybe a few books.
btw I think it was you Skybird that once brought up concerns over portable water filters. I have a First Need XLE water 'purifier'. It retains 0.4 micron particulates, bacteria, virus and specific toxic and carcinogenic chemicals. Kinda expensive, filters are 70.00 U.S. and because of what they filter dont last long. I usually change them out after 150 gallons. Good emergency purifier when crap hits the fan
