If you and your buddy who are moving it are a couple of beef eatin bad arse's then you will be fine. If either of you are not absalutely 100% confident, or scared you might trip on your skirt then you might want to call in the cav. Good luck!
play it safe and bring more than another person to help you. i wouldn't want a small mistake to break a tank of mines.. whether that be a hand slip or a trip. and also it might be too heavy. my 120 i think is already pretty heavy.
My tank when empty is meant to be 170KG... which technically 2 people could lift, but imo, it would be a much better idea to have at least 4 people lifting to save throwing out your back...
