2011 Tahoe PPV, 5.3, command vehicle (dual batteries), 160k, 2 wheel drive. Since I’ve owned it I installed upgraded full screen aftermarket radio with Sirius XM, computer reprogrammed, new: headlight assemblies, calipers, water pump, thermostat, all pulleys, (2) batteries, heated seats, seat covers, factory console, trailer brake control, dual exhaust, tires, plugs/wires, serpentine and a/c belt, rebuilt alternator. Oil changed every couple thousand miles, rear end fluid changed, transmission filter changed and fluid flush. Transmission shop advised trans looked new inside when they dropped the pan, so it may have been replaced. Vehicle has been a great beater, swap meet runner and tow vehicle so I hate to part with it. Engine started ticking the other day so I fear it could be the common lifter issue. I am on the fence if I should repair or sell. I would consider paying someone to repair as I really don’t want to sell. $2700
