We have a Sunbeam one purchased from Myer. It's more of a home use machine, but can't see any reason why you couldn't take it on the road. Would need to check the wattage during use for your power supply. We cryovac our meat and sometimes vegies, and it works brilliantly. We only run an esky and we can get 10 days with the meat. Plus there is the added bonus that the food stays dry when the bags get dropped into the ice slurry. We buy 5m rolls of the plastic bags so you can cut it to size to suit your needs. I think out machine is 240mm wide, and is the larger of the two Sunbeam models out. We have had ours for three years now and still working great.
