that is with out a doubt from a fork lift
i have driven them before and i have also hit things with them before and thats exactly what the damage looks like,
the said part is there no shocks on those things so if you run over a penny you feel it, so who ever hit your tank definitely knew they did it
sweeeet, hopefully we'll see some setup shots soon. Sorry it was such a negative experience for you, but hey soon you will have your aro's in their new big home.
