If you have a neighbor or friend to help, tell them they can have some of your tomatoes when they ripen. That's what I did anyway.

If it were me, I'd set up a simple drip irrigation kit and add a $20 timer that you put on your spigot. You should be able get everything you need from Home Depot or Lowes. It's a pretty easy system to set up and the timer is just like one you would put in your house for turning on/off lights.

Agree that some sort of automatic watering system is needed. They won't survive 2 weeks with no attention so I'd also line up someone to check on them every few days. Hopefully someone with some working knowledge of tomatoes, their pests, their need to be fed, and their water needs.

As to whether they will set fruit? That all depends on the weather and how consistent the soil moisture level is maintained. Sadly, trips away from home while gardening, even for a few days, seldom work well.

If they are in containers then the problems are even more complex.

A friend, neighbor, relative, automatic system (one of them) is a must.
Two weeks a long time anywhere and more so in Texas.
Some places there are people who babysit gardens at for a fee. hehe
