I have my parents campingaz stove circa 1970, ditto their stacking pans, larder, table, water carrier, and a load of other stuff too. All working perfectly so no reason to replace. Plus my childhood sleeping bag is still knocking about too.
Between DH and I we have a load of stuff that still gets used. I have my sleeping bag from the caravan holidays of my childhood - must be 40+ years old, I used it in the summer as it's thin! Camping gaz burner and stacking pan set from teenage cycling trips, so 30 years old. DH has a rucksack, bags and a roll mat that must be 30 yo.
My parents have been caravanning for 50 years, and whilst the vans have come and gone, their original set of green melanine crockery is going strong .
I like 'old faithful' stuff though. DS1 (11) has just got his first proper rucksack which I expect to last him through scouts, cadets, DofE, gap year, university etc etc.
...... what's the oldest bit of camping kit you have and still use?
Last weekend dh and I were talking about some of the stuff we have in our van which we still use. Some of the bits that I donated I acquired off my dad after he sold his motorhome were some of that they had in turn "inherited" off my grandparents when they had campervans when I was a child.
All still perfectly useable I have 5 mugs dating around 1988 (thermasulate - still keep my cuppa hot), our camping blankets from when we were in scouts and guides (32 and 28 years old respectively), one sleeping bag that's about 20 years old (still fine too) and some knives and fork camping kits bought from the national trust in about 1990. I still have some plates from 1988 but I use the ones from my dad more these days!
Maybe I'm a sentimental old fool but I can't bear to not use them but I can't help wondering if we are the only ones still using stuff generations old!
