G'day all , we have just got our panda and now needing to put a box on the front to put genie , hoses etc in , not sure if I should just run the one gas bottle to have more room or what , just wondering what other people have done and to what degree of success they have had without crunching the quarters on the tow vehicle , the van is a 17'56.2 std draw bar , tow vehicle is 2010 Prado , any help is greatly appreciated cheers, vince
