I haven't seen this information posted here before. Previous postings stated that the Titan Crew Cab could not realistically tow a fifth-wheel. I've also been told very recently by RV dealers that my truck could not used to tow a fifth wheel.
It seems that there are some options available if you are dead-set on a Titan CC/fifth-wheel combo, however, they may not be worth it in the long run.
The most promising choice seems to be the
12K Superglide by Pullrite.
This is a sophisticated fifth-wheel hitch mount that can allow the trailer to slide back away from the cab when turning. There are "gotchas", however. According to Pullrite, in order to use this with a Titan Crew cab, the front of the trailer cannot be more than 90" wide and the king pin must protrude at least 5" in front of the leading edge of the trailer. It's possible that a more rounded front cap of the fifth-wheel may allow it to be slightly wider. The other prohibitive factor is the cost of the hitch itself... over $3,000 MSRP!
When I asked Pullrite for examples of a unit that meets the required dimensions, they cited the Forest River Rockwood. I don't have a high opinion of the Forest River line; perhaps there are better options out there.
One dealer suggested that our Titan CrewCabs may be able to pull a type of fifth-wheel called a (ironically enough) "Titanium" by Glendale. I've seen articles on some RV sites which seem to confirm that the Titanium can be pulled by short-bed half-tons without the use of a sliding hitch. They have an unusual front end design that allows the leading edge of the trailer to swivel over the cab instead of bashing into it.
More info on these can be found at
the Glendale RV Titanium site.
What isn't clear to me yet, though, is whether or not these claims would only apply to the extended-cab Titan and that perhaps the crew cab would still need some kind of slider hitch with this one.
Anyway, I decided I didn't have time to continue pursuing a fifth-wheel option and ended up buying a travel trailer instead. I hope someone else will look into this further and let us know what they find out. My aim here is just to share that the question of whether or not a Titan CC can work with a fifth-wheel is not an unequivocable "NO", even if perhaps it is a debatable "not worth the trouble."
