WTF?
I am married with no tickets, 23 and have USAA. Our insurance for an 05 Scion TC and an 04 F250 is like $200/month.
I'm assuming the truck is the most expensive of the two to insure. I guess it all depends on the fine details of your plan and your cars. I know the deductible can make a big difference in the cost. I think mine is $500 or $1000, I can't really remember.
Also, location is a big deal. Maybe SoCal is a little more expensive than the DC area.
