I have used a hose on the high pressure side of the regulator, for stoves and BBQ's for years. It all packs up smaller than a couple of those tiny bottles, and is way more cost effective to use. I had used the small propane bottle in a crate before, but always found it in the way when it was not needed.
Like everything though, there is no one method that works best for everyone, and how they do things.
(I do sometimes keep one or two of those small bottles handy for quick stops or use away from the trailer)
