A better RV 4x4" Bumper Cap

thingiverse

A previous cap has been working well but I didn't like it... several reasons ... Anyway, I did this one in an attempt to keep it minimal and simple. Also, after using the Rhino hose I discovered that it would actually fit tightly in the bumper and it was just extra edge material that initially kept the collar from going into the bumper. So why not go back to the OEM cap? Well, the coupler end fits very tight and the original rubber cap needs the sewer hose well recessed inside the bumper so it's a total PITA to get out. This cap allows some of the coupler ears to extend outside the metal bumper edge so that it is easy to grab and remove. I used 1/4" diameter cylinder magnets epoxied in each corner and they hold the cap solidly in place for travel. It installs and removes much easier than the OEM cap!
