A 2008 CRV is flat towable unless the fact that it's a 4-wheel drive model interferes with that some how. Certainly the 2-wheel drive model is flat towable.
The absolute determiner about flat towability is the car's owner manual. Look for "Towing" or "Recreational Towing" for the official word on this.
You will need the following items:
A Base Plate
A Tow Bar
Safety Cables
Tow Bar Wiring / Lighting
A Supplemental Braking System
Expect a cost between $2,500 to $3,500-$4,000 depending on the equipment you purchase and if you DIY the install or have an outside shop do the install.
