Congratulations! Love Suburbans
Weakest link in all half tons (even higher class) is the rear axle GAWR. Been a while but IIRC...a half ton Suburban is around 4,xxx lb RGAWR
The main why higher class has +6,000 lb GAWR
Most all full sized TV's have plenty of power...again, the main limiting component is the rear axle
Plus, SUV's with that many seatbelts allows much to be loaded into the TV...and then the trailer tongue weight
Mostly a can do it, but longevity and performance (avoidance, stopping, getting it going after stopping on a steep incline, etc)
Much depends on how you drive, where you tow, how you load...
