Fort Leavenworth to Fort Lewis

[bob.stone34]

We purchased a TT two years ago to make moving more enjoyable in the military. We camped the past two summers in it but this is our first PCS/move with it. We will be moving from Fort Leavenworth, KS to Joint Base Lewis McChord, WA over 4th of July weekend (I know, bad weekend to be on the move, not by choice). I have reservations in the KC area and at JBLM but am looking for recommendations in between. We are heading north on 29 out of KC and then west on 90. The plan is to travel 300-350 miles per day with a stop after two days of travel. I have a 2 1/2 year old and an 8 month old so kid friendly is a big plus. Below is a list of where we are staying, I would appreciate any feedback. Washington State looking to prove difficult.

KC Area Basswood Resort- Already reserved
Sioux Falls, SD- Jellystone of Sioux Falls
Rapid City, SD- Kemps Kamps (extra day for Mount Rushmore)
Garryowen, MT- Grandview Campground
Gardiner, MT- Rocky Mountain RV Park and Lodging (Extra Day for SNP)
Missoula, MT- Jellystone
Mosses Lake/Ellensburg, WA- Recomendations? (will be July 4 night)
JBLM, WA- On Post MWR Camp Grounds (already reserved)

Thanks for any help you all can provide!

This is my favorite for camping in the Garreyowen Mt. area.
7TH Ranch RV Camp and Historical Tours, South East Montana RV Park & Campground

Take a little extra time for the Big Horn County Museum in Hardin Mt. Big Horn County Historical Museum & Visitor Center
You can pull out camp in the morning and hit the Little Big Horn Battlefield and on into Hardin for the museum, gas up and on up the road.

I really liked the KOA on the Yellowstone River south of Livingston. It's usually not as packed as Gardiner.

This corner of Montana is where I grew up.
