Don't EVER plan on selling or trading it in because what you did is highly illegal as far as the ROPS is concerned and if you trade it in the trade in dealer will have to replace it before it can be resold to anyone and you, as the original owner are liable for the replacement cost.
You obviously never read the sticker on the ROPS or in your owners manual where it states that modifying the ROPS voids the warranty as well as the structural soundness of it.
