9-year old Burley...I don't keep good track of mileage by bicycle, but I'm sure it's safe to say it's been ridden quite a bit less than yours based on your posts. I did have the rear trued this past weekend to help accommodate the V-brakes I've been trying to finesse. I will say that we took it to europe in cases that I built (S+S model) and I'm sure the whole thing exerted some significant lateral force on the spokes, but they handled it just fine.
