Thanks guys, it might not be 'needed' yet, but I'd rather err on the side of caution since I love this car and plan to keep it for at least another 100k miles. I know, I know, it's not Mustachian, but it works really well for us. I'll consider something smaller the next time, but we haul furniture, compost, tons of luggage, camping gear, etc. regularly and so far it has been fantastic.
