I'm in the process of planning an RV road trip for the last week in March and am looking for some personal feedback like I've read on other posts. We live in the Chicago area and my kids have never seen a lot of what our country has to offer. So, I'm refusing to buckle to the "Disney Pressure" and am insisting on an old-fashioned road trip. Ideally, I'd like to make the trip out west through South Dakota and over to Yellowstone and down to the Grand Tetons. However, late March would likely be a "crap shoot" in terms of the weather and that's a best case scenario. So, I'm considering heading SE to the Smokies and through NC out to the Outer Banks. Any feedback on either of these two routes, or completely different suggestions would be appreciated.
