To find the most accurate approach angle for your specific 2010 Chevrolet Suburban, you should consult:
* Your owner's manual: This is the best source.
* A reputable automotive specifications website: Sites like Edmunds or Kelley Blue Book *might* list it, but it's not always included.
Keep in mind that approach angle is just one factor in off-road capability. Departure angle and breakover angle are also important.
