My guess would be that it is a standard size for RV's. Replacement with another better handle might be the best solution.... For such an expensive RV, looks like it could be at least satin chrome or brushed nickel to be more durable.
Vinyl? If it doesn't come out looking good, or deteriorates it can be removed to start new.The handle has a light in the back half. The carbon fiber is a carbon fiber look vinyl. It has many uses. ...
Yours looks virtually brand new, given that it's 9 years old. Mine is just like yours but no LTV letters on it. I love the look of my handle as it is so durable and lighted. Just one of the few things on my Unity that doesn't have to be repaired, replaced or modified!I have been envious of some of the features of newer Unitys. Not so much with the entrance grab handle though. The glass area with the LTV initials is a light. Ignore the reflected greenery.
