I agree... it seems so odd that its only in the EL version... I have a 2004 Expy Eddie Bauer and it rides like a dream...so much so that I decided to jump up to the MAX (or EL) for the ever growing family!

I showed the shop foreman your post on what could be the problem and they are going to try and re-shim the driveshaft to see if it gets better... Problem is that my vibe is at ALL speeds and gets worse when the speedo goes past 70mph!

I wonder how they plan on selling brand new trucks that vibrate...maybe they will say its for 'therapeutic' sessions!
