Let me get yalls honest opinion, I had a Tundra before I bought my 2500. We had a trailer that weight a little over 7500lbs loaded, my Tundra payload was right at 1180lbs(lol), I had the limited 4wd TRD blah blah. After a few trips, my brakes started to have a hard time, could tell it was having a difficult time stopping trailer. I did some adjusting to the brake control and felt like it was doing better. On our way home from a trip on top of a mountain in Alabama, my brakes completely locked up and it was a nightmare. Shop told me that my whole brake system went out, booster etc. Never had an issue just day to day with truck. Do yall think the trailer caused this? I know I was over payload after the fact... I ASSUMED I had 1400-1500lb of payload based Google, never took the time to look at the yellow label(Hey Stupid)...
