A standard bed CC pickup truck pulling a 30ft (again hitch to bumper) FW?
Because of the amount of the fifth overhang over the truck bed, the actual length of both the truck and fifth will be about five feet shorter than both measured separately. Of your choices, I would think that would be a little easier to maneuver after a few dry runs getting used to the fifth's turning and backing characteristics.
The 'C' and the trailer will be around 45 feet long perhaps a little longer with the hitch, about the same as the truck (short bed/long bed?) and fifth. I would get the one you want and practice a little and you should be good. There are many on here that are adept at putting a 35-40 foot fifth where they want it so it can be done. Once a fifth starts backing up in a turn it tightens so in some circumstanaces it can back into tight corners. If you get a slider hitch (short bed) or if a long bed you can usually go to 75-80 degrees of angle depending on the fifth's front nose cap and that can be helpful in backing into tight spots as well.
