Whilst I don't have a Camino or experience of them, I have recently completed a purchase of a Sonder Frontier. From my experience the Sonder website is not terribly accurate, not long after going through the purchase, Sonder emailed to say the colour I'd ordered was unavailable. This choice of colour stayed on the website for another few week though.
Sonde also says that they will build the bike in 10 days, my build, which was stock, apart from the tubeless conversion option, took over 20 days to build. Unfortunately Sonder failed to communicate this and throughout their communication was poor. If they'd only sent an email from the beginning, saying look where terribly busy at the moment and the build will take longer than the stated 10 days, then I would have been satisfied.
Aside from the long build time and poor communication, I've been more than happy with the bike, it's been well built and rides lovely. The sizing information on the website is accurate and overall I have been happy with my purchase and would buy from them again.
