You don't say whether you have the long bed (7') or short bed (5.5'), though you do refer to "fifth wheel for short bed trucks"... usually trucks with less than an 8' bed are considered short bed. If you have a "long bed", the following may be of interest to you:

I went in to inquire about fifth wheel hitches with the same idea as you had - that I needed a sliding hitch to allow tight turns... I was advised that most newer fifth wheel trailers come with offset pin boxes to alleviate this issue with short bed trucks, and that I would be able to use a standard hitch with no danger of contact between cab and trailer unless you do something really stupid. This is with a crew cab, long wheel base (7' bed) '08 titan. The advantages of a standard hitch over slider I was told were ease of use and mounting rails were less obtrusive (price is obvious).

Unfortunately the only mounting hardware that was available was for one of the sliding hitches due to the "new" model (the lack of aftermarket support for the Titan is more likely). I've been meaning to inquire since then to see if hitches & mounting hardware are available yet or if not, when...

If anyone has personal experience or knowledge that contradicts what I was told, let me know.
