Scott and White Hospital in Temple and Providence Hospital in Waco are both outstanding Regional hospitals that would be able to meet your requirements and much more. Both Austin and San Antonio also have outstanding Regional hospitals as well. I think Athens would be a good choice as a community and as an area of Texas, but I have no idea how close to quality health care Athens might be. Personally, I'd probably elect to stay somewhere in the Texas Hill Country because of the beautiful sceney, birding, fishing, hunting, social opportunities, drier climate, etc. The temperatures aren't all that bad. We won't usually have a week a year of much below freezing weather. Anything more is usually considered abnormal. The four cities I listed above fairly well frame what is known as the Texas Hill Country. There would be many, many RV parks in a variety of ranges and services within this area ranging from outstanding Corps of Engineer facilities to State Parks to more budget friendly private parks and true RV Resort type properties. The choice would be yours.
