Pack by weight too - heaviest stuff on the bottom. Depends on your cabinet setup, but we keep canned goods on the floor of the floor cabinets, tea, napkins, cereal, etc up high. Obviously the vehicle will drive better/safer but also the weighty stuff doesn't acquire as much momentum when you're rockin' and rollin'
Putting things in plastic trays, both in cabinets and in side opening fridges, can really help with organization and said rockin' and rollin'.
We had a couple of drawers that would pop open frequently the first month we were on the road. Replaced the catches on those with higher pound rating catches from the same mfr. Problem solved.
