I am with you 100%.
For the next 3/4 years - I only need a storage system for 7 to 8 times a year, maybe 25 days, tops.
The other 340 days I need the rear space unencumbered (including back seats down) for bikes, dogs, building stuff, clothes, rubbish and the rest of life's detritus that needs moving houses.
So, it simple really: I want an efficient, well made, creative, flexible & comprehensive storage & draw system, incorporating a cooking device & fridge BUT that is fairly portable; i.e. it can be fully removed in an hour or so.
DOES IT EXIST OR WILL I NEED TO COMMISSION A BESPOKE VERSION?
