She's right... I've towed trailers for decades.. My current camper is a 30' 5th wheel.. I hardly know it's back there.. But I've sure seen some awful wrecks when a TT begins to cycle... You MUST have a superior hitch and anti-sway system installed with a TT. Even so, there's no comparison to a good 5th wheel..
The only con re: 5th wheels is the bed of the truck's not as available to carry other items unless they're small enough and/or situated in such a way as to not interfere with the trailer..
The longer distance between the pin and the axles of the 5er makes loading the camper less of a factor than a TT.. Those must be loaded very carefully in order to ensure you have the correct ratio on the tongue.. Many times the only way to find that out is to load it up and head for a weigh station or a farmer's elevator that has a scale..
