i've got one holding my tank down.
I've never had an accident so i don't know how good they are. But i am happy with it.
Oh and bacause the tank is strapped down (to 2 metal bars bolted through the floor) my insurers don't view it as a modification.
Have you told them about the size of the tank the size professionally fitted but a garage?, and been totally up front ? I tried minimal details all would insure me for vans, asking the correct questions cut the options to a few (this says it all imo), fitting a tank to a van is a mod (how ever anyone wants to dress it up it is) it affects the handling of a van. I hope to god people that are incorrectly insured do not find this out the hard way, more so if you hurt someone else by not disclosing all the right info when asking for a quote. I personally asked all the right questions to cover me and my business, I was not to interested in he money side more the cover when I found the right deals I shopped around asking the same questions. I would say to anyone reading this you do the same. DO NOT LISTEN TO PEOPLES VIEWS ON THE LAW OF CARRYING YOUR LOAD ASK THE PEOPLE THAT INSURE YOU.
I am not knocking anyone who has posted by the way, I am saying what I think to be correct, I may be wrong as could others, check yourself and get covered correctly is what I am saying.
