Hello from a soon to be new to the Pop-Up club member. We're taking delivery of an 05 Fleetwood Evolution 1 on Thursday. Actually, it's a few states away and family will be picking it up. I have friends with 06 and 07 E1s and I've noticed some visible differences between the years and would like to know what changed for the E1 after 2005. Here's a photo that shows an 05's right side: On the later E1s there is an exhaust panel or something like that aft of the wheel on this side. What would that be? Also both the 06 and 07 that I've seen in person has a stereo which I guess was an add beyond 05. I've measured an 07 to see how it will fit in our garage. Does anyone know if the dimensions of the 05s are any different from 07? Anyone know what my hitch height should be for the 05 E1? Thanks!
