Is there a minimum distance between the fifth wheel & the back of the cab/sleeper? The reason I ask is I have a RoG Peterbilt 359 that I want to convert from a 359-119 to a 359-127, which means moving the cab/sleeper back about 7mm; and I don't want to streach the frame. By leaving the frame at the stock length will it be too short?
Did any of that make sense?

Your kit's wheelbase is fine. Some extended hood trucks, like my old blue Pete, have just enough wheelbase so to speak. You would be surprised just how close the trailer's nose(with a reefer unit mounted) can be when the 5th wheel is slid all the way up, and you can still turn just fine. You can keep the wheelbase the kit has. If you plan on hooking up, just slide your 5th wheel back a little so it looks right.

True, but if the distance from the back of the cab/sleeper to the drives is too short, the trailer won't turn, right? On a static model it probably won't be too noticable like Ray mentioned.

I know about moving fifth wheels (not sure how they move & still manage to haul those incredable loads), but moving king pins? Did I understand that correctly? Can the kingpin be relocated on the trailer, or is it optional locations from the factory and once it's there it's there?

Well Jim, kind of both. Years ago, because of STRICT length regulations(esp. Iowa), some trailers had 2 kingpins. You would hook up to the one further back to shorten it up.

Didn't areas that had bridge length formulas have trailers with the king pin 16 inches from the front to maximize length to haul maximum weight? An east coast trailer would have a 36 inch? A sliding fifth wheel can only slid back to the center of the tandems.Maybe the era of truck makes a difference?
