We traveled for 7 yrs all over the USA....back roads mostly
We just out the things in the cabinets and drawers.
Even traveled with a full place setting of Noritake China (Moms China) in the glassed door cabinets.
In 7 yrs only had one item break......I dropped it into sink :S
Just slowly open cabinets/fridge after setting up.
Jar of jalapenos fell out once.
Things stay put pretty well W/O extra precautions/efforts.....relax.
(And if hubby still isn't convinced have him pack/unpack that stuff in boxes for a few trips :B )
