Places to overnight along I-80 and 84

Willard Bay State Park in Utah, north of Ogden on I15/I84. Litterally right off the freeway at exit 357. Go to stateparks.utah.com. If you're going to be mid-week, getting in shouldn't be bad. Weekends can be busy, especially in the spring.

Through the Wyoming portion, almost any community is small enough on 1-80 that the Walmart thing is a good choice. I great little quite RV Park is in Lyman (KOA) that we liked better than the RV Park right at Fort Bridger (historical site), but the historical site is kind of cool if you like that stuff. Beyond the fort and grounds itself, it has a "rent a room and a garage" on-site that was part of the historical automotive traveling thing (not for modern use). I forget the name, but we had an excellent Docent. It's kind of charming.

We use a helpful Ap called RV Parky for various "overnight" parking. It is pretty good showing which Walmarts (and lots of others) allow or don't allow, but still have to make certain. Always best to check with management, and obey city ordinance signing.

If you're ready to stop around Boise drive a little farther (get through that traffic!) and stop at Ambassador RV in Caldwell. Huge pull-through spots - easy for an overnight - about 1/2 mi off I-84.

In Sidney you can park at either the Cabelas truck lot or the Good Sam lot. I have stayed there many times. Traveling west the next stop I stay at is the Walmart in Rock Springs, Wy. It's about an 8 hour drive between the two points.

early april may be a little chilly at emigrant, a lot warmer at wild horse casino.

Several Oregon State Parks on I-84 along the Columbia River, they are really nice and reasonably priced. You probably won't need reservations this early in the year, but it would probably be advisable to give them a call if you get a chance.

Depending on how far/long you want to drive per day, there's Little America WY -- fuel stop there and a goodly sized parking lot. About 600 miles from Kearney to there. If you want to stop at Laramie WY, there's a KOA at exit 310 as well as a Pilot Travel Center, about 375 miles from Kearney.

At Sidney NE you have the options of Cabela's truck parking or Walmart parking.
There is also a dump station at Cabela's truck parking.
Between Cheyenne and Laramie, exit 323, is a rest stop at the Lincoln Memorial. It is high country, so it will be cooler at night.
The interstate rest stops in Idaho and Oregon are very nice, as are the ones in WA.
The Flying J truck stop at exit 54, East Boise, ID, is small but has a dump station if you need one by then.
