The wife & I have this 'understanding'. I don't complain about the 'stuff' she has in her galley or one of the big overheads filled with craft stuff. She does not question what I carry around in the basement which contains everything up to a spare water pump & trailer axle.
We have no house, no storage place to put unused stuff so it all gets carried around the country.
At the begining of each season there is the annual basement tidy up & clean up when a box worth of stuff usually finds its way to a dumpster.
