Actually, let me re-phrase my post.
Are you mad?
Do you really think a tank strapped to your rear seats is a) legal, b) safe c) roadworthy d) worth the risk of snapping your spine in the process of propelling you through your windscreen in the event of an accident as the straps fail to do what theyre intended.
I seriously cant believe others on here condone this.
You know the answer to this post already, its in the title.
