Tested out the new camp stove with my metho burner yesterday, timed it boiling a pot of water from cold, it took 5 minutes so not bad for a tiny little spirit burner (Trangia). My whole cooking setup weights less than 1 kg. Base Pack weight is sitting at around 7-8 kg with food but not water (an additional 4 kg, 2 litres per person). Little miss can carry her own sleeping bag and mat but they are light enough that adding them to my pack won't make a much of difference. Son 3 will borrow my small pack for his tent, sleeping bag and mat, he will carry his own water. He won't need the extra stuff like cooking gear as that is all shared equipment, but I may move the first aid kit to his pack to even out weight distribution.
