I received an email from a Love Your RV reader that goes by the handle HerveVR. He was kind enough to let me share his ingenious fix for the cracking ladder cap problem.
When reading in the Tips and Mods section about the entitled subject and having the exact same problem with ladder end caps of the ladder on our RV, I want to share with you the solution I have came upon.
After a close look, I found that the root of the problem is the poor design and simply replacing the end caps will just postpone the next issue.
In fact, the step is supported only by the longer screw through the tiniest and weakest part of the plastic cap; this cannot support the weight of a normal person climbing the ladder.
So I made square angle supports out of aluminum angle stock (to avoid dielectric corrosion) and fixed them with Pop Rivets.
I did a complete ladder rebuild this pass summer . Removed it from the RV and took it all apart . Bought all new bolts, screws, endcaps, star nuts, and upsized the screws to fasten it back on the RV . Its made a world of difference but I can see where adding the angle brackets would make it even stronger.. I also am trying to figure out how to make a support from the bottom step to the bumper for added support for the ladder . I think that would take a lot of stress off the ladder when in use.
