I have a 2002 suburban with 5.3 and tow package with the Nivomat self adjusting shocks, I will be towing a travel trailer with a equalizer weight distributing hitch with anti sway bars rated at 12,000 lbs capacity and 1,000 lb tounge weight capacity. A prodigy brake controller. The trailer weighs in at 5,974 lbs and plus whatever we pack in it(clothes, food, dishes, chairs, etc.) I believe we will be at 7,000 to 7,500 max camp ready weight and the trailer has center kitchen and elecyric brakes. Anyone on here have any experience towing close to this weight and your thoughts? In Ohio, Michigan, Indiana mostly, so no major hills. Thanks for any input.
