If U tow a TT, Do U have a tonneau or shell and bed slider?

I bought my truck used and it had a cap and Bed Slide installed. I towed a travel trailer with it for a year and the Bed Slide was wonderful for accessing all the gear in the bed plus was a real back saver. Sold the Leer canopy and Bed Slide to an appreciative buyer before getting the fifth wheel. I now have an Extang trifold tonneau which is nowhere as convenient as my previous gear.
