I hope you and your family is prepared when the "real world" comes and slaps you around. Your children are going to find that parents are not going to let their children go over to their "house" to play. They won't get to know their neighbors because they will always be changing and they will have to learn not to trust their neighbors because you will never know who will be staying next door for the next couple of weeks.
You are living in about 250 square feet of living space. There isn't going to be any privacy. When the Texas summer rolls around, you don't spend time outside, so that 250 square feet will become your entire domain. Most RV AC units are close to inadequate for the Texas heat, so you might find it uncomfortable at best and downright miserable at worst. We have a 45 motorhome and the 3 AC units don't keep it cool enough for me, so we don't do Texas in the summer, that's the time to move north.
Being frugal is fine and dandy, but be careful it doesn't have long lasting negative impacts. After all, the purpose of working for money is to have money to use to benefit yourself and your family. be long term smart.
