Sacramento to Parkersburg WV

If you're taking I-80, there is a steep grade at Salt Lake City. Take I-15 north at SLC to I-84 then back to I-80 not as steep. Near Laramie WY there is a 3 or 4 mile pull to the top where there is a rest area. We've been out west twice and we're from flat Florida and did fine in our DP pulling a small pickup. Just take it slow. I would say 5 days (4 nights) would be better.There will be some construction. 5 days would be 8 hours driving per day plus rest and fuel stops. The trick would be to get up and leave very early each morning so you can arrive at the next stop before dark. We have stayed at the following KOA's on that route. Although KOA's are pricey they usually have pull thrus which is nice if you're only staying one night. Wendover KOA, West Wendover NV 2. Cheyenne KOA, Cheyenne WY. 3. Des Moines West KOA, Adel IA. 4. Indianapolis KOA, Greenfield IL. We do have other campgrounds we prefer but they are not right off the interstate and do no have pull thrus. Last time we were in IL, I-70 was very rough especially at the OH state line.
