It is what you are comfortable with. The steepest grade I have driven was 10% and I had no trouble and was not bothered in the least. There are people who are not comfortable with 3% grades. I have driven Hwy 87 from Phoenix to Payson ,and the reverse, and never touched my brakes in my car and my RV yet people have had to replace all of there disc's on there cars because they are so warped from overheating there brakes on the same drive. On your route if it was me it would be the 160 hands down
