I'm pretty sure that Pugslyyy is correct in terms of driving the vehicle. However, I have heard that some insurance companies may resist paying claims (including liability) if the vehicle was over the GVW. It could be worth checking with your carrier in that regard.

The big thing that I have found with insurance companies is that if there is anything different about your vehicle, go ahead and declare it to them. I've had the experience where an insurance company denied a claim, but after I had them review the declarations they covered it fully.
