I found this site today www.carrentalsavers.com and got a intermediate SUV (Ford Escape) or similar using Budget 139.00 a week SUV plus the $30.00 off weekly rental at BOI (Boise Idaho).

NEW! Budget Discount - Get a Compact Car for $119/week or $17/weekend day or a Intermediate SUV for $139/week or $22/weekend day!
Use Budget BCD D454300. Valid for rental pickup by 12/15/13 at participating locations. Blackouts may apply. Not valid in New York Metro, Martha's Vineyard, Salt Lake City.

I think this is an Excellent Deal 10 days for 249.86 total all taxes included !!
