Well thanks people for your input, the reason that I have it sitting back on first cross bar is becasuse in the winter I put the gear basket and defelctor back on. The bar sits directly behind where the gear basket sits. And also I have the sunroof to take into consideration when mounting this.

Suspect2: are you in Baltimore? The reason I have emergency lights on my peronsal vehicle is because PA emergency services are not state funded so we don't have the funds to purchase 'company' vehicles as of yet but we are working towards that. You are correct in worrying about insurance issues, but my insurance is aware of what the X gets used for and also the company is insured against personal vehicle damage if responding to an emergency call and I am not at fault.

Thanks again guys for your input.
