Other possibilities to avoid leaning: Some growers will stop growing indeterminate tomatoes after they produce 10-12 braces of fruit and just call it a day. If you do this you might have a second set of plantings ready to go in mid May to June to take over from the older plants you have stopped. I am doing this now with some of my plants, replacing the indeterminate with fast growing determinate and semi determinate.
You could also choose to allow one of the suckers on one of the lower scaffolds to grow in parallel to your leader and when the original gets too high make that the sucker the leader and eventually remove the old one.
** If you really wanted to go full greenhouse this you tube shows how to do it! (Make certain you have a market first!)

That is big operation with a lot of money behind it. They probably ship a lot of product to Europe.
One little high tunnel is enough for me. Automating it helps me learn things that will help me at work, plus it will run the tunnel while I'm at work. Selling veggies is probably not my thing but building/installing tunnel automation would be my type of thing. I have no plan for that but you never know.
Just found the tutorial video that I need for using the PLC to run my drip irrigation. It will be surprisingly easy. Even the Pulse Watering will basically be creating one instance of an ON timer, then an OFF timer and repeating that for 4-6 pulse watering sessions, 10-15 minutes long per day.
Tomato plants are apt to keep going for at least a month. That will give me time to monitor/test. Pretty much the same soil so whatever works up here, will work down where the tunnel's going, just a matter of scale. Rain will cancel observation up here for some time since there's no plastic roof.
Just bought a gas tank for my splitter. Old one got water inside of it and rusted from not being covered and evidently, a crappy cap. Drove the property yesterday looking for dead trees to cut for firewood. Looks like I can get half my wood here and I'm pretty sure I know where to get the other half. I also have a ton of live trees here I need to cut down and those can be for next year's firewood.
