Questions for newer dakota owners

98 Dakota Club Cab, with 3.9 v6 automatic bought in 2001 with 20,000 miles on it about 170,000 on it now, towed a nearly 4,000 lb car on a 1,000 lb trailer to race track for about 3 years, never any problems with that. Replaced heater core, 2 water pumps, rebuilt right front brakes 3 times(should find and fix the underlying problem), have to recharge the air conditining once or twice a summer. Replaced all four ball joints, and 3 or 4 sets of tires. Towed the trailer great, sometimes got kind of sketchy stopping (no trailer brakes) had the trailer push me through a stop light once, luckily it was 2:30 in the morning so there was no traffic.
