I have an epirb with 2 way satellite sms.
Have a remote area first aid kit. (With no official training how to use it)
Will have a bit of space if people need some.
I have a spot with tie downs for 2 x 20L jerries.
If yous think I don't need much spare fuel for me.
I also have a 10L I could put in for me.
(road range is about 750 to 800 dependant on right foot etc)
Steel jerries with good seal only, as I will be breathing inside the Paj

(or I can just bring my 2 known good ones for others to use?)
Other stuff could be carried, but keep in mind my dog is fluffy and smells as bad as me
Rear section will be dog free, but only lighter stuff goes behind the axle.
