Hello!!
Sorry to take so long to get back to you. Somehow I missed the notification that I had a message.
We have a piece of property directly next to our office that you're welcome to stay in. You can plug in, but will need a super long cord.
Go to 1107 South 8th Street, Austin, TX and check it out on street view on google maps. The big green office building is us. The Google Car caught my parent's coach is in the north parking lot. Since this was captured, construction around our building has gone nuts so we can't have a coach in our lot (because we need the spaces), but you can pull into the grassy area directly north of the lot. We actually have some friends staying there now.
There is electric and water, but no sewer. There is an RV park about 1/2 mile away that will let you dump for about $10 if you need it.
Pecan Grove Rv Park - 78704 (South Austin) - Austin, TX
