The transmission may also be a sore spot - mine has been fine and I tow a car trailer fairly often - but I change the fluid pretty regularly which has kept the trans happy. I would worry if the trans fluid has never been replaced.

The shocks on the magnetic ride system are durable and I wouldn't want to replace them as they are expensive. Did you run the codes yet?

Ditto on the brake lines.

If they have not already been replaced I would recommend doing them all at once (not just the ones that look like they need replacement).
