Here is the improved XLII handle that comes in the upgrade kit. The kit includes all necessary linkage and brackets, as shown below. I haven’t installed my handle yet, but I’ve noticed that the new XLII models and entertainer buses come with this handle.
My original handle isn’t broken; it’s just difficult to unlatch the door from the outside, as if the handle doesn’t provide enough leverage to open the latch. I’m confident that this kit will address the issue, but there seems to be more to the story. This kit costs $454, not $100. I’m starting to wonder if there was another upgraded handle released at some point or if people were given the same handle as their original when they bought a new one. I’m not sure what’s going on, but this new handle looks like it will fix the flimsy design of the original XLII handle.
