We always stayed at Canyon Lake outside of San Antonio, in the state park (Potters Creek) very peaceful and clean, only electric and water but they do have a dump station. Pads are huge and spread apart. Lots of wildlife and the deer are on your front porch every night looking for handouts.

If your wanting something close to downtown there's Travelers World , I have only seen it passing by, its huge and close to the riverwalk.

If you want to be closer in to the Riverwalk and The Alamo then checkout Traveler's World (www.travelersworldrv.com).  We stayed there 2 years ago and enjoyed it.  We didn't have a "toad" with us so we used the city bus, which stopped right in front, to take us downtown.  It was about a 10-15 min. ride to the Riverwalk for 50 cents each!

Depends on what you want/plan on doing. Although we normally stay at Madina Lake, when want to visit around S.A. we stay at Jelly Stone park on the near south side.
You can walk accross street for bus. Also ride the various shuttle around town.
Have found that parking down town is almost impossable.
Of course going to the Military bases requires driving. Staying at the Fam Camp (if qualified) is also hard because they are normally full.
Of course for us old folks, nothing is still as it was in the early "40's"

We are staying at Top of hill rv park in Boerne ,Tx. this is a nice full hookup park that is 31 miles north of San Antonio but same distance from Fredericksburg, and is central to a lot of Texas hill country attractions
