I am considering whether or not installing Slide Out Toppers (covers) on my 2012 Landmark is worth the expense. I have read several threads on this forum regarding miscellaneous issues re: slide out toppers but not whether or not they are worth the expense. This is my 2nd RV and neither have had Toppers, so any input would be appreciated. If in fact the consensus is favorable, is there a Brand that is superior. Great Forum. Thanks. Dave.
