I have an 06 Ext. Cab SE 4X4 with tow package. I need to tow a 5200 lb Chevy on a 16ft. flat bed tandem with trailer brakes and a controller that I installed just tonight. I'm guessing that the trailer is around 2000 lbs. I have about 11,000 mi. on the truck and just had the oil changed, but not the diff. or tranny. Should this matter? I have towed alot of things before but nothing this big. I am going from Arizona to Idaho. I personally think that the truck should handle it, but I just want to hear some other opinions. I need feedback fast since I am leaving in two days. Thanks.
