RUST is the enemy.
I agree 100%.
It is very concerning if you see rusted brake lines. Another indicator is if you hit the main frame just forward of the rear tires, with a hammer, and it showers down rust, I would stop right there and kindly leave.
We live near Chicago where salt is used on winter roads. Our rig is stored in our heated garage during that time. I bring it out well after the spring rains have washed the salt off the roads.
It would be different if we were snow birds or winter campers. I would not let that get in the way of enjoying our rig. But we use it seasonally anyway, so it is easy to apply best practices. If we ever sell our rig, it will be a "Hot Buy" for the like-new condition it is preserved in.
