Lonne, Glad you confirmed all is as it should be, thanks to your LED. I'd like to have a dash indicator to tell me my cruise control is activated; If I switch screens on the Aladdin, yes I get a Cruise On indication, but a glance at an LED in the dash would be safer.
Steepest grade for us so far was Teton Pass, between Jackson Hole Wy and Victor ID. 10% grade. I did at one point, have to brake and downshift to slow, all the while using the Jake brake in HI (6 cyl) position. That brought us down to 15 or 20 mph toward the bottom (east side) of the hill, the tight corners required a reduction in speed, not the grade.
