7 on 7 off - Reefer or Dry Van? The Good, The Bad, The Roehl Way?

Finished Phase I, II & III and loving it! Glad I went reefer. Getting more miles per week than I was told I should and can't complain. Glad I went with ROEHL except for the Rolling Over Every Hill Last part....17mph in 5th pedal to the floor in some areas under a heavy load.

 

No. This is when I hit 69 mph going down hill pedal to the floor in 10th then start heading up next hill and speed drops. As speed drops I go to 9th at 48/45 (revs at 1500) etc and keep repeating going down. The red warning over rev taught me the max I can maintain going down through the gears. I climb at 1500-1600 just on the edge before the red light warning pops up. Rarely pops on now up or down hills. If I try to downshift any sooner the light would come on. Unless you and others just let it come on to save momentum for heading up steep hills. Any tips? Thanks.
