You mean like a b'twin bike? No, we don't have anything like that, the closest comparison would be Schwinn probably, and yes, that's a Walmart bike.
The fact is that the €200 b'twin bikes aren't ready for touring either. At least not touring in the Western United States, where there are thousands of square miles with a) no cellular phone service b) no one living within a 3 day walk, and no water within a 3 day walk and c) no cars travelling on your road for hours at a time. If you break something and can't fix it, and no one will stop to help, you could easily wind up dead.
SRAM components without even a "3.0" on them and Shimano "Tourney" components (or worse, those that are just referred to by a model number, like M194) are just begging to be broken; they're only made to last a few hundred miles, and they're typically not road serviceable. And twist-grip gear shifting, which (if I remember correctly) is how most b'twin bikes hybrid and commuter bikes work, is impossible to repair if your on the road. Not a great idea in Arizona or Montana, especially if its 110 degrees out.
If you can't find something used, maybe the Schwinn Sportera will suit you, at least it has Altus stuff on it. You will have to spend at least $300 on it though.
In the end, its up to you. If you go with Walmart, spend as much as you possibly can to at least give yourself something maintainable. Good luck.
