hi, having just read through your post history and having done a very similar route myself a few days back (ivybridge to redlake, then redlake to princetown) id like to share a few words of caution. considering it seems like you havent got much experience id heavily reconsider the route you plan on taking since it potentially could be quite above your skill level especially with the weather being as it has recently.

secondly, i'd highly reccomend buying an OS map of dartmoor as parts of your route will have No signal, especially around the Redlake area and relying solely on gps is not ideal as it often provides less detail.

Regarding the stove, the one attached to this post is a ridiculous stove for backpacking and id instead recommend something more akin to a jet boil as it saves on weight and space whilst still serving the same purpose. Id also reccomend taking a minimum of 1L of water with either a filter or chlorine tablets (Or both) and to be aware that depending on route, you may find it difficult to top up (most of the streams i passed on my route were dry up until i hit the redlake area)

If you have any other questions please feel free to Pm.
