Watch the weather forecast. May need to take a more southern route.
There are internet sites and paper campground directories for looking up and calling ahead to ask about their places. I personally like the paper directory. I have the Woodalls but it might be known now as Good Sam.
We wish you the best. I had to start over myself as well.
Just take one day at a time and ask for God's guidance and strength.
Remain flexible on you trip.
You can do it.
Ps. Just curious. What trailer do you have and what are you towing it with?
RV people are very friendly and willing to share. Be sure to ask for advice and suggestions along the way.
