A 2003 Executive has the folding ladder. This is carried through 2006 for the Executive. In 2007 the Executive received the taller roofline with built in awnings and a 2-piece ladder.
The 2003-2005 Signature will have the same folding ladder, but 2006 model gets the taller roof and 2-piece ladder.
Stromberg-Carlson makes universal RV ladders that can be adapted to fit. An Executive will need the straight version.

To repair the original folding ladder we made some new lower brackets and a sleeve to repair a cracked section. I also replaced most of the standoffs. Eventually I need to replace the entire upper right side tube to get rid of the repair sleeve.
