I like TT better, but it is a personal preference.
Me too! But perhaps for different reasons. I like the bed of my truck for stuff, the lower overall height of the TT, and the less weight on the tongue vs the pin for a similar size coach. But, beyond a certain size I think the fifth is probably a better tow, is overall (tow vehicle and fifth) shorter by about five feet for the same size coach as part of it is over the truck's bed, and (at least for toy haulers) the hitch/pin weight changes significantly between loaded and unloaded as the toy load is all behind the rear axles and I think a fifth handles that variation in weights better than messing around with a WD hitch every time you pull the trailer depending if it is loaded or not.
