Which would be the better route for pulling a heavy 5th wheel westbound from Sturgis, SD to Billings, MT?
We're not overloaded by any of the gross weights but am near the limit for GVWR of my 07 Dodge 3500 5.9 CTD. The automatic tranny is downshifting more and more as I approach the Rockies and my mpg has dropped from 12.8 to 9.
Should I expect to creepycrawl up every pass from Sturgis to Seattle? I guess I'll find out between Billings and Bozeman.
