Squatty, You don't have to worry about driving 100 miles on the original tires. I've driven 2000 miles without issue. Others have driven multiple times that. I have to get a spare anyway so I figure it's a good time to upgrade. Hopefully someone will buy my extra original tire to use as a spare or someone can use it on their classic car.
I did get to speak to a very helpful Forest River representative yesterday . It seems our recall letter was sent to the wrong place-right name/house number and town-wrong state.
After talking to him I truly believe they will do a good job correcting our Shasta .
