Need hitch help with a 2015 Ford F-150 (5.5ft bed) and Reese Revolution

Hi,

I'm new to fifth wheels (though I have done quite a lot of research), but not to conventional towing.

I just bought a 2015 Rockwood Ultralite Fifth Wheel, with the Reese Revolution hitch, which pushes the rotation point 22" back from the king-pin.

The problem is that my 2015 F-150 (Crewcab, 5.5ft bed) has a very short distance from the back of the cab to the axle center which, as best as I can measure, is 27.25".

That gives a total of only 49.25". Assuming that the king pin is centered exactly over the axle (and not 1.5" forward as some folks have suggested, and I'm not even sure if that's optional) that's only 1.25" of clearance if the trailer is at 90 degrees (96" width, so 48" half-width), but of course we need at least an extra inch since the distance from the revolution's rotation point to the front corner of the trailer is 49", leaving basically zero clearance.

So ... I have a couple of options as best as I can work out ...

1. Don't turn sharply (not liking relying on this one).

2. Use a manual slider, in addition to the Reese Revolution, so that I can slide the king-pin back behind the axle when making extra-tight turns, still using the offset of the Revolution. This seems like a viable option, tho' with the usual concerns about having to get out of the truck to manually move the slider back.

3. Lock the Reese Revolution 'arm' (what's the proper term for the arm between the king-pin box and the king-pin itself ?) to function as a regular king-pin setup, and use a Superglide 12K to handle offsetting of the rotation point.

This last one has both positives and negatives, and I'm not sure if it's even a real possibility.

The positive is that, although it's still tight, the fact that it adds 0.75" to the rotation offset at max helps. Additionally since the Revolution king-pin is 5" in front of the leading edge of the trailer (rather than the rotation point being 17" behind the leading edge) there's no concern with the extra distance from the rotation point to the front corner, so the max width of the trailer is worst-case, so with 22.75" offset plus 27.25" from cab to axle that gives me 50" offset, so 2" clearance at 90deg (assuming that the front of the superglide is exactly over the axle ... can anyone confirm this ?)

Of course there's the concern with moving the weight back off the rear axle, even when making gentler turns (I gather than the superglide moves backwards progressively, so the weight is back some even when only turning at say 20deg)

Next concern is whether it's even possible to use the Revolution with the Superglide. I've read folks suggesting that it's not recommended, and that it may not be possible to get a suitable locking plate for the Superglide that will fit with the Revolution.

I've also read concerns that, due to the shape of the Revolution's 'arm' it may interfere with the top of the truck bed when using it as a conventional king-ping arm, but I am a little skeptical of this since I'd have thought that Reese wouldn't have even made locking it an option if that were the case.

At the moment I'm leaning towards the manual slider (unless there's any powered sliders, rather than the superglide-style auto-sliders, which would eliminate the need for getting out of the truck), since it gives me plenty of extra clearance when really needed.

Hoping to order the hitch today or tomorrow, since I'm hoping to pick up the trailer in 1.5 weeks.

Thanks in advance for any help.

Here is my concern on this, not knowing more on your F150. I have serious concern that the F150 is even big enough to handle your 5ver. Looking up the specs on the various Signature Ultralights, the lightest 5ver dry weight is 9108lbs and up to just shy of 9600lbs depending on your model. Now add the 1000+lbs of stuff you will add to you 5ver. I am pretty sure the 9108 is over the limit for the F150 even before you add supplies and necessities.

I just checked Ford's website and for the 2015 model year the max towing capacity (depending on actual model) for a F150 is 9100 lbs, some models are as low as 5500 max.

Even if your model has the max tow capacity and you are in the lightest Signature Ultralight you are 8 lbs over max without putting even one thing in the 5ver.

the lightest GVW is 9108 for the signature line, the lightest UVW is 6886, and the F150 can be option up to 11000lbs towing "3.5L EcoBoost® V6 3.55 7,756 kg - - - 5,443 kg ( 11974 lbs) " this is for a regular cab, not that I think you would ever tow a 5ver at this weight but they are rated this high.

According to Ford the towing capacity on my (upgraded) F-150 is 10,200lbs (for a fifth wheel ... or 11,900lbs conventional towing).

http://www.ford.com/resources/ford/g...0_r1_Jan12.pdf

I have the SuperCrew 145" wheelbase, 4x2, with the 3.5L twin-turbo GTDI V6 and the 3.55 ratio locking rear axle

The FR Rockwood Signature Ultralite 8281WS has an unladen weight of 7948lbs, and a max loaded GVWR of 9446lbs, well clear of the 10,200lb towing capacity of my truck.

I do see now that the manual shows different info than the towing capacity general info screen I was looking at, and that I misread weight of gvwr as dry.

I cannot answer any questions on the 5ver towing as I do not have one but I am sure someone will.

Have you also checked the max cargo capacity of your truck? I was planning to get a 5er to tow with my 1/2 ton Chevy and everything was good except the cargo capacity. It needs to be big enough to cover the pin weight of the trailer, the occupants of the truck and anything that will be carried in the truck.

The cargo capacity of your truck should be on a sticker on the drivers side door post, the same sticker as the tire inflation PSI.

Hello leefl
Sticking with your original question here is a video that might help with your setup and hitch.





I have the Reese 16K pin box (its a slider also) in my F150, and I have not had the opportunity yet where I had to use it.

I also have the Reese 16K with manual slider and I also have not yet had to use it. My F150 however is a 6 1/2 bed but my son has one with the 5 1/2 and has had the same results. That's the route I would take. Discount the information you are receiving about your truck's towing capabilities. I doesn't matter what you tow, as long as it's a half ton truck there are some on the site that will tell you it can't be done. My special ordered F150 (2015) with the aluminum body has a carrying capacity of 2900 lbs and a towing capacity of 12,200 lbs. Easily within the realm of many nice 5th wheels. That ECO boost engine will amaze you. It tows my 32' Chapparal Lite like a dream.

I have exactly the same hitch on 2015 Ford F250 with the same bed length. Hitch is mounted 1.5" forward and have the reese sidewinder hitch. It works great and have about 7 inches of clearance between camper and back of cab when 90 degrees. Only issue I have with it is it is a pain to hook up. Got to be perfectly lined up with the pin and receiver both side to side and front to back. Bought some rods to stand on the trailer and in bed of truck and works much better on lining up. Also put plenty of grease on it. Been pulling fithwheels for many years and this is by far the hardest to line up. It does make manuevering forward and backwards much better as the pivot point being moved 22 rearward makes the trailer turn quicker going backwards unstead of having to pull up 20 feet to move over 4 inches it only takes a few feet to make the camper respond. It also makes the trailer track more closely to the truck while maneuvering around in tight spots like gas stations.

The 7 inch clearance is when using the Reese 16K manual slider, in addition to the SideWinder/Revolution, correct ?
(otherwise with just the SideWinder/Revolution and a fixed hitch the clearance would be negative with the hitch mounted 1.5" forward)

Is the hitch the square tube slider ?

or the round tube slider ?

Thanks so much for your help
