A few years ago we drove from Indiana to Great Falls,MT, on to Moab,UT and back home on I-70. Last year we went from home to Montana to Grand Coulee Dam to Portland,OR. to Ontario,Or. to Missoula,MT. to Rapid City,S.D. to Cheyenne, Wy. to home. I do not have an exhaust brake and I never felt unsafe or got my brakes hot on either trip. I figure it is my money so I spend it as I see fit. I drive defensively too. Lots of space between me and one in front. Have never had to make an emergency stop in any vehicle I have driven in over 50+ years. JMHE.
