I'm currently planning our trip next summer to the Badlands, Custer and then beyond. We are planning to rent an RV for the 2.5 week trip and "camp" along the way. My question is: How difficult is it getting around the park in a 26-28' RV since this will be our only means of transport? I'm pretty sure we won't be able to do Needles Hwy because the tunnels are too small, but can access Sylvan Lake from 89. I'm also pretty sure we can do Iron Mountain as those tunnels are bigger and some have by-passes.
Thanks in advance for your comments and insight!
