Need a little advice.. Leaving central California, heading to Dickinson, Nd. Trying to avoid climbing months if possible. Are the climbs through, SLC, and Wyoming Ok? Or should I add several hrs...
Between SLC & Wyoming on I-80 there is a pretty good climb - depends on what you're trying to avoid. We had no problem with it whatsoever with our rig. You may be able to avoid some of that climb if you use I-84 from Ogden east to I-80, but you'll catch some of it.
Not sure Idaho will help much. We have mountains too. :)
