Sidewinder 5th Airborne

[chipster]

I'm looking at purchasing a 5th wheel toy hauler and this Sidwinder Kingpin seems to me like the way to go with my short box. I like the side winder airborne for these reasons....1. built in shock/airbag 2. ease of hooking up and disconnecting. 3. my hitch will be able to hook up to other trailers if for some reason I have to( No catch plate).

My question is what hitch to I get with this Sidewinder....dual pivoting, are they all adjustable for height height.

I did like the Super Glide but I understand you have to be more in a straight line to hook up and I would have to purchase a Airborne kingpin also to help with the chucking.

Thanks

There are some missunderstandings about the sidewinder pin box by Reese Mfg. I have a 5th airborne Elite. I installed it myself and have used it for one season and driven about 4000 miles so far. I have a 16000# Reese RP30047 hitch (dual pivot).
First if you are researching, download the installation instructions to get an idea on how the setup works. Also be aware that the sidewinder cannot be used on all fith wheel hitches. The instructions detail this.
Second, Reese does not do a good job of explaining and promoting this unit. Hence the rumors and wrong ideas.
Third, the sidewinder does NOT change the load point on the TV. It is about the same length as an extended pin box so the pin to trailer position does not change. It just moves the pivot point back to the pin box attach point.

I am an engineer and have studied my sidewinder constantly while I've owned it. Here are my observations:
1. Hooking up to the sidewinder is a new challenge especially if you have a lot of experience hooking up a regular pin box. I have read many forums where people cannot get the pin to go fully into the fifth wheel latch. With the standard pin box you just align your hitch to the pin and back in until it stops. With the sidewinder you have a lock plate that keys into the slot in the back of the hitch so the sidewinder (the part that pivots) must be parallel to the trucks longitudinal axis. I know that sounds complicated but all you need to understand is what to align to when backing in. Instead of looking at the pin, watch in your inside mirror and center the trailer pin box attachment point to the middle of your rear window slide. If you do not have a sliding rear window you can place a piece of colored tape vertivally in the center of the window. If the pivot part of the sidewinder is slightly missaligned to the slot in the hitch it will move over by itself or you can push it over until it will enter the slot. The lock plate will then enter the slot all the way and allow the latch to close. then do your normal pre-tow hitch latch test.
2. Sometimes the pin is difficult to unlatch. This is an ongoing issue for me though it is becoming less so. Though I am not sure why yet, obviously there is too much pressure on the jaws to be able to pull the release. I am thinking that it is a combination of the tightness of the lock plate to the slot and the air bag pressure. When it is difficult to release I lock the trailer brakes, reverse the truck to push the pin forward in the hitch. I also remove more weight from the hitch by raising the trailer more. That all seems to help. Next outing I am going to try removing the air pressure from the airbag to see what difference it might make.
3. The pivot is impossible to move by hand. The instructions say to lubricate the nylatron bearing and thrust washer with grease and to torque the four pivot plate bolts to 45 lb.ft. This results in a locked pivot that will only pivot while connected to the truck. Also after about 2000 miles of towing, I checked the bolts and found they were becoming quite loose and I have to tighten them periodically. I am trying to communicate with Reese about this as this issue has safety concerns. When the bolts are any looser than the recommended torque, if you pivot the pin box you can see the bolts cant to one side and back. The problem is that the trust washer is too thick and the bolt plate cannot bottom out on the post. i would like to sand down the washer but I want to hear what Reese has to say about this.
4. Towing and manuvering is better with this pin box. high speed stability is exactly the same as before but the air bag definitely cushions the chucking. Turning around in a tight campground is so much better as I can jacknife the trailer so much farther than before(over 90 degrees).
5. The pin box and hitch combines to make a lot of racket when stopping and starting. This is due to the multiple loose joints in the system. There is play where the hitch mounts to the rails, play between the pin and jaws, play in the two pivots in the hitch and play in the lock plate to the slot. it is not a safety concern but I did scare the #$@&% out of a lady toll booth operator.

In summary I would recommend this pin box but if you are not very good at hitching or aligning you may become frustrated enough to decide it is not worth it.

So if it raises the front 4 inches you have to have a real low hitch or

or in my case replacing the slider base with non slider base lowered 1.5' and springs lowered (raising rear) got it level. Depending on your present setup may or may not be a problem.

The sidewinder also has to be pretty straight to hitch but I hear after some use that the pinbox can be swung sideways by hand to align it.

No...You would not need to buy a Airborne Kingpin to help with the chucking. My 7 year old Superglide holds the kingpin so well it does not allow any chucking. If you do decide to buy the SuperGlide, I recommend you do NOT buy the Airborne pinbox, until you pull a few times. Then see if you still need to buy the Airborne pinbox. Most likely you'll not need it.

Yeah that`s what I was thinking. If it tows good.... end of story.

I have been considering the Airborne for some time, and spent several hours the other day searching and looking at videos. I never thought of the effect it would have on towing stability.

I have been reading these forums since before the Sidewinder came out and have been watching threads on Sidewinder. There was a lot of talk when the first came out where members thought there would be a lot of stress in the wrong place, etc. but I yet to see one thread to that effect and I believe that there are trailer mfgs that have them standard equipment or options.

I recently put one on my fifth but have only towed 40 miles with it so not much I can say about it except if you didn't know it was there, you wouldn't know it was there.

I believe that the stability of a fifth wheel comes from the weight it puts on the rear wheels which the sidewinder doesn't change. Possibly at high speed very abrupt and sharp turns there may be a difference but not much. The very little driving I did in and out of traffic, I couldn't tell any difference.

I was sure that I was going to get the superglide, but the sidewinder seemed to me to be a much simpler answer to the problem.

Per the sidewinder manual, it raises the front 4".

Im not one in favor of the Sidewinder pinbox due to the 22" extension from the kingpin point in the hitch to the turret where the 5th pivots.

Additionally you have to block the Superglide from sliding.

At least someone sees that like me the side winder part.

p.s. i thought you could lock it so it wouldn't slide.

There is about a 2.5" difference in the height of the Sidewinder due to the long extension. If you wanted to tow this 5th wheel with another vehicle you may need to make some height adjustments.

Most of the better hitches have the side/side pivot and are vertically adjustable.

Im sure I would not mix a Superglide with a Sidewinder.

Would not use the sidewinder but the Airborne Kingpin box with the Superglide.

You can be +/-16 degrees to hitch/Unhitch in a conventional manner. You can hitch/unhitch at more severe angles by lifting the hitch plate over the saddle and pinning/unpinning the hitch plate from the saddle.

But regardles of angle, the pin must be centralized to the receiver. If off too far (left to right) hitching can be a problem.

But the angular spec is not a big deal at all. And in fact is better for the trailer anyway. Hitching at a severe angle can put a heavy side load impact on the elevator legs. That is never a good idea. As it can cause damage to the elevator legs. A straight on hitch is much better because the thrust is in alignment with the wheel chocks.

just talked to Pullrite....have to use capture plate. Guess I could get Pullrite and add airborne kingpin down the road.

Do you have to be in a straight line when hooking up or unhooking?

Not that I can recall, and I can't quickly think of a way you could.
