2002 GMC Sierra SLT fully loaded pickup truck - original owner

Truck has had 1 owner. We bought new in 2002 5.3 liter V8 Runs very good and has plenty of power All 4 tires were bought new about 5,000 miles ago Has a Snugtop lid to cover truck bed Locking gas cap mud flaps on all 4 tires each of the 2 front doors have a wind diverter shield that surrounds the windows the hood has a wind, bug deflector shield or diverter installed things that are an issue rip in driver’s seat rip in rear seat passenger side of truck was crunched - however, the dent does not affect the opening of both the front & rear doors on that side as both doors open and close fine. sometimes the ABS brake warning light will light up on the dashboard. However, this light that comes on and goes off has been happening for the past 50. 000 miles or so. The GMC dealer said the brakes are fine and it is just a defective or faulty sensor. The cost to replace the sensor, however, was more than I was will to spend as the light was not a bother as long as the brakes still worked fine.
