Don't know how you find your current TT, but if you're in WA, there's a few narrow places in WA & OR. There's a really narrow bridge in Grays Harbor, one or two narrow bridges on 101 on east side of Olympic peninsula and the Deception Pass Bridge that come to mind.
We're currently in Newport, OR and it's pretty tight along some sections of the 101 here especially with people who park too far out from the curb. All you can do is point your TV down what *seems* to be the centerline of the road and pray you don't hit anything on either side. Then there's the occasional RV-er coming in the opposite direction that moves too close to the centerline or slightly over to avoid a parked vehicle on their side. Haven't hit anything yet... :E
If intending to do a lot of travelling all over, you might want to stick with 8'? Even with a standard 8' wide TT, I can't see very well on the right side as the awning tubes block the view. A trip on a WA state ferry could be "interesting" too with a wider TT.
