Trailer Brake Gain

Thank you everyone for your input and advice. I must admit the steep grades on alt 14 were unexpected. I never really thought of the down hill slop when planning my route. I did a lot of research before I bought my 2013 f 150. Knowing the weight of the trailer I was interested in, Videos forums etc. The trailer weight is 5,400 lbs empty. I figured I was under 1,000 lbs added weight. Propane clothes 1/3 water tank for stops. I am well under the GCVWR. The power going up was exceptional at that altitude with the twin turbos. I am thinking of upgrading the brake pads for safety. even though we are not planning any mountain trips in the near future. Experience goes a long way in situations like this and I hope to gain lots of experience in the future enjoying our new rig on many family adventures. Again thanks again for the input and safe travels to everyone.
