I want to go back to Yellowstone too. 10 days and feel like we barely scratched the surface. Also had to cut a big leg off that trip due to a neice getting married ( I was her florist) so we missed the Tetons, Colorado and Utah. That could be the next one and maybe add going into Canada to see Jasper and the surrounding area.
You definately met the RV challenges this trip but over all from our vantage point you handled it well . Don't let that experience stop you, things happen from time to time when you RV..frustrating , yes but just keep going and enjoy the trip once it's done
I think the key to Yellowstone is you need to stay in the park - centrally maybe Fishing Bridge but I'm not sure if we fit and we aren't set up for non-electric any length of time. The drive time into Yellowstone (in addition to the 140 miles of Loop) takes a lot of time - especially with entrance traffic. DW mentioned Utah also.
One reason we loved the South Dakota state parks - fill the fresh water tank and we were good for 10-12 days or so.
