>3. More maneuverable (though also harder to learn to tow if you’re not already used to it) because it pivots at the point where it connects to the vehicle.
5th wheel trailers help with this (so I've been told by family members that have them).
Can confirm. I've been fifth wheeling for >20 years. They're much easier to tow and you don't need as much length behind the tow vehicle for an equivalent amount of space (because the bedroom is usually above the hitch point). They're also much easier to hook up in the first place because you don't have to repeatedly back up the truck "blind" to get the tow vehicle into the perfect spot.
Fifth wheels can seem scary to people who are not familiar with them, but the benefits are numerous if you can overcome that fear.
I can also confirm. A fifth-wheel trailer with the proper size truck is very stable; even in severe cross-winds.
I use a gooseneck adapter on my RV since my farm trailer uses that and it's a bit more difficult to hitch up but you get used to it quickly.
Before COVID used fifth-wheels were very cheap -- my current one is a 2016 model I bought used for $17k in 2019. Things are a bit more expensive now but I figure the used market will probably go back to normal by next year.
They don't affect maneuverability all that much when compared to a standard travel trailer. However, you get a lot more living space in the same effective length due to the portion between your pin and rear truck bumper being now livable space.
They do however TOW quite a bit better than a travel trailer as far as comfort. Going from a 28ft TT to a 40ft Toy Hauler yielded a lot better towing/reduction in driver fatigue over long trips (also went from a half-ton truck to 1-ton, so some differences just there as well).
Wasn't familiar with this concept. Funny though: in my language, "5th wheel (on a car)" refers to someone being as useful as... well, the 5th wheel on a car, i.e., not useful at all. The "on a car" part is often left out.
(Sidenote for anyone wanting to argue the usefulness of 5th wheels: I'm not my language designated responsible for sayings and common phrasings. Also: 5th wheels tend to be the emergency spare wheels - which obviously do have a use.)
