A.E.,
I agree with those who have said driving I-80 from Omaha to Sacramento should not be a problem. I have done most of the stretch from Wells, NV to Omaha in the last 2 years and only remember a significant climb eastbound from Salt Lake City (4300') to the WY border (6700'). You, of course, will be going west and dropping 2400'. You gain about 3000' crossing the 450 miles of I-80 east to west in NE so you never really notice it. From western NE to Cheyenne you gain about 2000+' the last 50-100 miles. Again, no big deal. As you cross the 400 miles of WY, your almost always between 6500' and 7500' so there is some up and down by no big climbs. I've already mentioned that you "drop" from WY into Salt Lake City as you cross the Wasatch Range. From SLC to the Nevada border is vey flat. From Wendover on the UT/NV border the road is a lot more up and down than WY. There will be a few 1-2,000' climbs the eastern 200 miles of of I-80. The last 200 miles to Reno don't look bad. You're on your own from Reno to Sacremento.
At first I thought your comment about the lack of reviewed parks on I-80 was strange. Then I realized that you are from Florida where it is hard to go 10-15 miles without being within a stone's throw of an RV park. While you don't have that kind of RV park density on I-80, there are towns with decent parks every 100-150 miles or so: Lincoln, Grand Island, North Platte, Ogallala, Sidney, and Kimball, NE; Cheyenne, Laramie, Rawlins, Rock Springs, Green River, and Evanston, WY. West of Salt Lake City the pickings are a bit slimmer until you get to Reno. Remember, you are not going to find the big, lush RV resorts like you have in FL.
Obviously, some of these parks are better than others - check the reviews.
By May the snows should be over as far south as I-80 but you can never be sure. Enjoy the planning and have great trip.
Thanks for the great info..yes we have RV parks here on pretty much every other corner ...Ha! so I did notice they are not that way in the great west but we will make due with overnight stays.. Thanks again...
