When just meandering from place to place we use a lot of US, State and rural roads/highways.
When heading north out of the FL pan handle, US-231 is a very nice highway. We travel it to Montgomery, AL and then connect up with US-82 over to MS.
We found an ideal overnight RV Park at Troy, AL, Deer Run. It's family owned and managed and has a little of everything, including fishing lakes/ponds. It caters to our particular traveling habits, FHUs with CATV.
