I think it is a great idea for rural areas where it is difficult to get to a good shop. Personally I seldom shop over the internet because with out fail on the rare occasions when I see something that I just have to have and I've succumbed to shopping online, I have been disappointed with what I bought. Colours and textures just aren't the same when looked at through a monitor. On the other side I also like to feel the fabric, so I say go for it once you have nutted out all the pro's and cons. If you already have the vehicle and start up costs are kept low then why not?
