Ok, so I have a GMC Topkick 5500 with an aluminum flatbed that I normally haul gooseneck trailers. The height of my bed is 49" and I'm getting a Cyclone 3800 . This is my first 5th wheel. I'm worried about having to re-work my bed or losing my ability to haul my goosenecks. A buddy (w a40' toy hauler) is recommending an Anderson ultimate 5th wheel hitch but that puts my height to pin at 63". I don't have the trailer yet so I can't see if this will be acceptable or not. It seems that most of my problems center mostly around height. My gooseneck ball is recessed a couple inches in the bed as well and I don't have a B&W hitch in it. (forgot that earlier). I'm open to any suggestions. It's too bad that Topkicks/Kodiaks don't have more standard fit options Thanks in advance

Well, the Anderson really is and skirts the leverage arguments that I've read so much about for those adapters. Funny thing is two of the three dealers that we talked to about buying our RV from was going to put an adapter on it and let me ride out. The current one that I made a deal with is adamant that I not use one for voiding the frame warranty. Have you heard of that Anderson hookup?

Well.......................I would no t chance using a Gooseneck adapter on a NEW rig.........it will void your warrenty.

So if there was a demand for a Gooseneck, don't you think the Manufacturers would offer it ????

More frame bracing , strength needed, due to leverage issues..

Don't believe me, look up "Lippert frame issues"....nice reading for a couple of weeks..L.O.L.

Is 63" too high for pulling the cyclone. I don't have it yet so can't check. Most 5th wheel connection will also keep me within 4" of this height.

I used to have a pop in gooseneck and a 5th wheel that dropped into some "pucks" so that they. Could be pulled out. I just can't remember what brand it was.

no way to know without seeing it hooked up to your rig, every trailer is different. Don't know about your hitch but mine is height adjustable somewhat, it has 3 sets of bolt holes to move it up or down.
