Have camped in Scotland quite a bit although from r22 & r44,in very remote places and always hoped it would start the next day!.Main reason for posting although it may be obvious weigh everthing it's amazing what sleeping bags etc weigh and I managed to buy a 2 person tent that weighs only 2.5kg and by the way if you like red wine with your evening meal a box of wine weighs a lot less than the equivalent amount of bottles.Also we use things like lightweight drinks in cups like you get from coffee machines etc as they are a lot lighter than normal mugs etc.Doing everything carefully have managed it in the r44 with 4 pax all within limits.All off airport of course in a heli but might be of use.
