I was gone last Thanksgiving and I was so worried about mine because it is a 6 hour drive out there and we stayed 6 days ( ick the reason i say that is because i am 13 years old so you try spending 6 day and 6 hours drive there and back with ur family ) but I was able to buy a portable tank about 3/4's the size of a 10 gallon tank and in the car we own we have an electric plug in for like charging you phone so we pluged in the heating pad and put them in the back seat under my feet i was able to pack all of their needs in a semi-big purse.
