I live on the west side of Atlanta which makes it easier to pick up a east west route. I go to Houston 1 or 2 times a year to visit DD who lives in Magnolia, TX. I will assume you are retired and if you are over 62 years old get an "America the Beautiful" pass if you haven't already done so. $10 for a lifetime and it give you free admission to most national parks and 50% discount on campsites at Corps of Engineer campgrounds (and other government grounds). I like CoE campgrounds because of the cost. I like to keep my travel down to no more that 250 miles a day. My first stop going west it Gunter Hill CoE on the west side of Montgomery, AL. Get a campsite in the Catoma loop as they are all full hookups, $13/night. I then head south to US 84 (4 lane all across Mississippi) and stop at another CoE campground called Service or Service Park, $13, just west of Coffeeville Al. The best place to go and do nothing on the bank of the Tombigbee river which has ample barge traffic to watch. Their actual address is Silas Al about 30 miles from the Mississippi state line . Then my next stop is at Riverview RV Park & Resort in Vidalia, LA just across the river from Natchez, MS right on the Mississippi River. Very nice park, they take Passport America discounts. A good place to spend an extra day and tour around Natchez. Then I head on west/southwest again and go down through Alexandria LA and go to a CoE campground just west of Jasper TX called Sandy Creek on a big beautiful lake with a cost of $9/night. Last stop for me is a Harris County park called Spring Creek Park in Tomball TX. The best part of that park is it is full hookup and is FREE for a 1 week limit but would give you time to check out the Houston area. We took a day trip from there to go the George H.W. Bush presidential library at College Station. From there you can go a little west to San Antonio for some Texas history or go south west and go to Big Bend National Park, that is on my bucket list to see. Just make sure you have ample fuel and groceries because it is 100 miles from nowhere. I can't say much more about campgrounds in Texas but have seen good reviews on some campgrounds around Kerrville.
I guess the first thing is you have to decide where you want to go and what you are interested I seeing.
