Re: Towing a fiver with a 9' flatbed
rosewood1 wrote: you could also have someone miter the corners of the bed I am a welder/fabricator so I could do that myself but I do use the truck around the farm and sort of hate to lose the corners. The way it is now I can load 4 pallets on it on either side of the gooseneck ball (2 on each side). But if you notice the bed tapers in front to match the cab width. If I have to lose too much on the corners the pallets would be hanging off the rear corners if I cut them too much But I may end up doing that if the fiver I find that I really like needs it :) I just really had no clue if there was a standard distance. You would think they would all be made to some sort of standard but with all the hitch adapters, different length pin boxes, offset adapters, sliding hitches etc I guess I will be able to make it work one way or another. I am planning on going with a smaller fifth wheel (25-30 footer 7000-10000#) so the pin weight will be pretty low (2000# ish) so I think I could even mount the hitch 12" behind the rear axle and would probably never notice the difference on the steering. I mean after all bumper pull travel trailers are 4'behind the axle :D Thanks for the input and ideals everyone. I will keep this thread updated as the process goes forward.

Well this is interesting. I look forward to finding out more heights & distances, but at least I know there is at least one trailer (Roger10378) that would work fine the way it is without having to modify the bed (cut corners) or mount the hitch WAY behind the rear axle. I did not realize the pin boxes came in such a variety of sizes and lengths and as well as being adjustable. I have a couple RV dealerships about 40-50 miles away. Might just have to go do a walk around and get an ideal of what is typically on them.1.3KViews0likes0CommentsRe: Towing a fiver with a 9' flatbed
I know to get max capacity the hitch does need to set in front of the rear axle....but I am planning on buying a smaller fiver 25' to 28' so if I do have to place the hitch behind the axle for clearance I doubt the weight transfer will be that great. Looking at 7500 to 10000 GVWR trailers. I know that bumper pull TT is WAY behind the rear axles but I want the fiver to pull as good as possible.

Hello all. Hopefully a question is OK for a first post. It is what led me to the forums here. I have a 2008 F350 Dually with a 9' long 100" wide flatbed on it. I am wanting to use this as a tow rig for a fifth wheel but I am not sure the corners of the bed will clear the front of the trailer. I have looked online but can not find what the standard distance is on a fifth wheel from the king pin to the front of the trailer. Currently it has a fold down gooseneck ball (not recessed) that is actually already a couple inches behind the rear axle. I know it should be over or slightly in front of the rear axle but this was a used flatbed I bought to replace the rusty factory bed. So the gooseneck ball is behind the rear axle a couple inches. With it being a 9' long bed I am not concerned about the hitch to cab clearance or any cab hits. And since it is a flatbed I do not have to worry about it hitting the top of the bed. But I am concerned the rear corners could hit the front of the fifth wheel in turns. I have NOT purchased a fiver yet or I would just go measure it. Another thought is this bed is 3" taller than most beds. Is there a standard height of the pin box? I have not decided if I am going to use a goose neck adapter or fabricate a mount for a fifth wheel hitch. I have a Reese 22K fifth wheel hitch and the height on it is adjustable.....I am just concerned that the taller than normal bed height will make the top of the hitch set to high if I go this route. I know you want the fiver to set level when setting on the fiver hitch to make the axle load equal. So basically, is there a standard measurement that manufactures use from the king pin to the front of the trailer? And is there a standard hitch height that the manufactures use to design the trailers? Thanks a bunch for reading this long winded post and any help you might give. Below are some pics to clarify what I have to work with. Hutch in Oklahoma Moderator edit to resize pictures to forum recommended limit of 640px maximum width.4KViews0likes12Comments
