Auto insurance for travel in the U.S. - please help

Folks,

I am looking for a bit of help. Hopefully someone out there has
experience with this and can help. I have found some information by
googling but still have questions.

My situation is this. I am a U.S. citizen and a Greek citizen. I
currently live in Greece and plan to visit the U.S. for about 6
months. I will be shipping over my vehice and need to know how I need
to insure the vehicle. I understand that I can drive the vehicle in
the U.S. for up to one year (without extensions) with the Greek plates
and registration. Insurance with my Greek provider is not possible
for the US. I have found temporary insurance plans for coverage in
the US which is intended for foreign citizens. What is my best
approach here? Do I just give my Greek citizenship/Greek passport and
ignore my US citizenship? Or, is it possible to obtain insurance from
a standard insurer as a US citizen for a foreign registered vehicle?
I would like to fully insure the vehicle (ie: full coverage). If
anyone can give some pointers or direct me to further information I
would be very greatful.

Thank you,
Jason
