It took me 2 yrs to convince my husband to camp and our first camp was in 2010. After a fairly disastrous first time borrowing a tent and having little kit we decided that if we were going to do it, we should do it well. So now we we have a pretty good set up. By the way we have 2 kids now 15 and 12.
5 man tent for anything more than a weekend, 3 man tent for weekends (you can stand up in both and DH and I sleep in the living space of the 3 man when we use it).
Both tents have open extensions. This is the key part for me. It means we can sit sheltered from the rain if necessary although camping for us is all about being outside, by the fire.
In the extension I have a kitchen unit with my single burner stove. Store all crockery and food there too. I also keep my cool box in the extension.
Bedding: we all have SIMs in fact DH and I changed from a double to two singles as they are easier to pack (and sometimes I camp with the kids only). Sleeping bags for all usually but in hot weather we take cotton sheets and duvets instead and it takes up no more room.
I usually have a supermarket delivery to the campsite on day of arrival so very little food to pack, however I have usually prepared something for the first night that can be easily reheated, just in case there is a problem with aforementioned delivery.
Camping chairs, one each and a couple of tables too.
I have a spreadsheet which I print off a few days beforehand. We live in central London with not a lot of extra space so have a local storage unit where the camping gear is stored (amongst other things), so it's a quick trip there the day before to load up and then pack our personal belongings and we are good to go.
Recently got a bike rack so obv if we are taking bikes that's a 20 job to load.
On return I just ask the kids to dump dirty clothes by the washing machine and usually 2 or 3 loads will sort it.
All in all it's worth it for me. The joy of the outdoors and the campfire are very special.
Not sure what I'll do when the kids leave home, maybe buy a camper van 😂
