Knox: we are also a two teacher family and we got a small 21 foot bunk model RV a couple years ago.
We try to take it out a few weekends each Fall and Spring to nearby places, Tawakoni, Ray Roberts, Eisenhower, and Bohnam. If it's a three day weekend a little farther like Mineral Wells or Dinosaur Valley.
Then we use it as much as we can in summer when we are both off. Short trips during the middle of the week are great because most parks are pretty empty when it's not the weekend. And every other summer we are trying to do a longer out of state trip.
Our only big trip so far was 15 days out to Grand Canyon and then up to Colorado and back. We are hoping to do another long trip this summer of Covid calms down.
It isn't a cheap hobby but it's something a two-teacher income can support and we have the time to enjoy it.
I pay 50 a month to store it, the thing cost me around 14 grand new I think, then I put in about 2 grand of upgrades and another 1500 in repairs already.
Now the wife is eyeing an upgrade and the one she wants is over 20 grand so I'm not saving any money over more traditional vacations.
But the family time is awesome and the kids love it.
