I have a friend with a 2500 series Suburban with a 8,800 GVWR and 454" engine. It tows a 10,000 pound trailer with a 1,000 pound hitch weight with ease.
Chances are that your Suburban is not that heavy duty, but we would need to know the GVWR and rear axle weight ratings of YOUR vehicle. They are on the drivers door sticker.
Also do you have a factory hitch, or not? Factory 7 wire connection?
Those are fairly easy to upgrade while installing a electric brake controller. I installed a 7 wire plug and electric brake controller in my RV in about 30 minutes. Your wiring experience will vary. . .
