I just changed mine out. I have the Morryde cre3000 and wanted to change them out for new ones. I measured everything and ordered the 35 inch equalizers. When I received them in the mail, they were larger than the existing ones on my fifth wheel. I called Morryde and they asked for my measurements. I gave them the measurements and they said that I definitely need the 35ís. They said that I have the 33ís on right now, which Forest River must have put on by mistake. In short, go to the Morryde website and look at the qualifying sheet that will tell you what to measure in order to get the right one. Good luck.
