Thanks for the response. Our trailer does have brakes and work pretty well. Infact I usually lock up the trailer tires well before they should due to varying loads. The trailer brakes actually help stop the rig a little better.
The RV is a 2016 so it has the latest iteration of brakes.
J-d, when we panicked stopped, the motorhome brakes never locked up, just didnt have much grab. This is why I was thinking the brakes are glazed. I just had the front wheels off and the pad thickness and rotor looked fine. Of course I didnt take the pads off to see if they looked glazed. My fear is the previous owner just rode the brakes all the time and glazed the pads. I think I will have new pads put on and cut the rotors and see if that helps.
Pnichols, we always have tow/haul mode on.
