I've never talked, or read about an F53 owner that has these. But, they're add sure makes them sound pretty good. (Heck, it it would automatically take out the trash too - I might get a 28' Bounder as my Toad, just to see how they really perform:)!).
Suspect these would be on the higher cost end... But, if holding onto a coach for along time, that costs pays dividends with 'smiles by the mile's'.

Best to you, and all,

(And of course, assume you've done all the Cheap Handling Fix approach to taming the F-53?)
