This year, I upgraded my tent by buying a smaller one (from 5 man to 3.5 man) but tall enough to stand up in, has a covered porch area for rainy cooking/getting out of wet gear outside and also small enough I can put it up alone (5 man is also tall with pitch but needs at least 2 competent people to pitch, my previous 4 man had no pitch, too short and is so old it's starting to fail badly so reserved for Scouts events as we have a marquee so I only need to sleep there).
I am looking at a trolley and a pressurised shower (both decathlon). I had a non-pressurised shower bag before which was great but DH put it away still wet one autumn and it was non useable come spring with mildew/mould.
I also upgraded this spring to a fire pit - which was tested on Cub camp and is fab! Campfire at the tent, up off the ground, and while we didn't test the grate, it seems possible I could cook on it too.
Last year, I went from a 4 season mummy sleeping bag to a 2 season envelope style. Sleep sooo much better when not melting and able to turn around in it!
And 3 years ago, I got the Decathlon 3 panel solar panel to recharge my power bank for phone, lantern and ipad. TBH I use it at home as well now. DSis has the 2 panel version which is fine for phone and lantern.
I know that sounds extravagant, but I do pretty minimal camping - no ehu, no "proper" kitchen (1 ring gas stove on the table to cook that is cleared off to eat, 1 plastic tub holding everything else for kitchen), a chair, decent sleep set up, couple of lanterns, hard sided cool box which uses ice blocks). Bring hiking boots and swimming gear and come home mucky and tired 😁
