Have no idea what to expect in vibration.Will the closures on travel trailer cabinet doors work? Can I leave the cats in the trailer while traveling

at least for the first few days of yowling? Didn't think so

The floor cabinets need to be fastened to the metal ribs ? Do not plan to do any offroading. Will be transporting o2 bottles-I use an insulated cooler to carry them in our vehicles with padding between them. We are going to ger a 2000 watt Honda generator for his oxygen machine so we can boondock or in case of power outages. I do NOT want anything airborne while traveling. Still planning on an 8x18 Continental Cargo or Cargo Mate with 3500 lb drop,leaf spring axels.The remarks about bungee cording the frig door and making sure about the microwave tray have been helpful!
