We have only gone for up to 2weeks so far but we use 52L plastic tubs to store our clothes,hubby and i share one, girls 6m and 9yr share a 2nd, and boys 8yr and 11yr share a 3rd, hubby has made a timber slide for them to stack on which slides down one side of the trailer, we were using individual suitcases but found it time consuming to pack into the trailer because it was like doing a jig-saw puzzle......we got caught last big trip with shoes, we only packed thongs for the kids because the trip before it that's what they mostly wore and we had 3 sets of shoes to five people which just wasn't practical packing wise, on this last trip we went to take them go-karting but they had no enclosed shoes so luckily we hadn't brought new shoes for school yet so shopping we went......we are still working out what to pack and how many sets of clothes to pack, but i always pack a weeks worth of undies, and we are considering buying fishing shirts for everyone, my hubby has one and loves it, warm in winter, cool in summer, and they have sun protection ratings, only thing they are not cheap, boardies are great with kids, last trip they ended up in boardies and rash shirts all day......it's great to hear everyone else's tips for myself for our future camping trips
