We've stayed at Alamo Rec-Veh Park in Alamo. That might meet what you want.
Alamo Rec Their rates for the season are reasonable - several friends stay for a 3-month visit last winter -
RatesWe also have several friends who stay at Casa Del Sol in nearby Donna
Casa Del SolWe have also stayed at some of the Encore parks in the area -
Alamo Palms RV Rates for those corporate owned parks can be harder to determine.
All of the parks I've mentioned are close to US-83/ I-2 in nicely populated areas. There are no troubles from 'illegals' but do be aware this is a metropolitan area of close to a million and half people.
Mainly working level families, many have been in the agricultural business in the area since long before there was a state of Texas, even a United States. Median incomes are in the low teens.
All of the parks I've mentioned are gated and have a minimal level of security, but while theft is very rare, it is not unheard of.
That said, thousands of people leave their winter homes (rv's, park models, mobile homes) for months at a time with no problems.
We feel completely safe in the area. And visiting our dentists in Progresso, Mex, and cross border shopping trips or just for an afternoon's food and entertainment.
Others do not.
Spanish is spoken by the vast majority of the people, and while it is preferred by many, we've never had a problem anywhere.
