Thanks.That being said. The Shoshone forest does offer both! Around the Cody, Wyoming area. IF you are wanting to stay in Yellowstone, Grand Teton, NP, etc. Make a reservation! If you need any Wyoming ideas, let me know, that's our back door.
All of the mountains in those western states that you mention are likely to have a huge amount of snow on the ground in March. And you'll want to carefully check weather before venturing into the mountains, since it can change very quickly and sometimes be very mean indeed, even forcing you to spend a night somewhere (gas station? Side of the road?) that you don't expect, even though there can also be some wonderful weather there.
There's always the potential for avalanches (yes, even on the Interstates), and other causes for road closures, such as in Glenwood Canyon (western part of I-70 in the Rockies), but there's also some gorgeous scenery.
So when your route is better defined you will want to start checking weather at least several days before you get there, just to note trends and the changes in the forecast (a 7-day forecast of clear could overnight turn into 6 inches+ of snow). And the "chain law" is also something you'll want to know about -- basically when snow is even possible you'll need good snow tires and/or chains, by law, as well as by good sense.
You'll also want to be aware that on weekends some of the routes to ski areas (often major through routes) can have major traffic jams.
Now that I've cautioned you, you can usually make it through if you're willing to wait for a day or so should the bad stuff be there. If it's not, you'll have a beautiful drive.
If you can find a time to get through when there is no snow on the roads in the high country, you can get by without them, but just be sure you're not in a bad situation without a set.Would you recommend me to get a set of tire chains ..
If you want hookups you only have two choices, Rex Hale and Wapiti. Both are a ways from Yellowstone, but nice campgrounds. The Shoshone on the highway to Yellowstone has lots of first come first serve campgrounds. Some open like July 1st... when are you going.Thanks.
Our original plan include Yellowstone and Teton however looks like both parks are still closed by late March/ early April
We've been in Yellowstone in Summer ( Mammoth) and Winter (old faithful resort) but always while on vacations in Jackson
Never in an Rv.
Still Wy is one of my fav states so even if the parks are closed we plan to spend a few days in the area
I would look for your recommendation in Shoshone forest
Any other advise highly appreciated
Thanks
The weather apps are so accurate now and each state has a road conditions site. We live in snow country, until we head south and I just watch the weather, cameras, etc. If there is snow we just sit and wait it out.. wind I. Wyoming is as bad as snow..We intent to leave Florida around March 10
After many stops on the way to the West I plan to arrive around Early April
Which I'm aware there will still be snowy with even a possibility of a storm
I would be ready like you said to stop for a night or two if necessary ..
Would you recommend me to get a set of tire chains ..
I'm not planning to drive under those conditions but just in case ..
My exp with tire chains wasn't pleasant.. I use it before in a vehicle while we went in glenwood and was a traumatic experience to install . So I don't want to even think on an Rv
