1. Block all trailer tires with wheel chocks.
2. Make sure trailer landing gear / jacks are resting on a firm, level surface.
3. Towing vehicle must be stationary with auto transmission in park

Always follow operating instructions to secure trailer to tow vehicle.
Make sure the hitch is secure before towing.
Prior to towing, ensure all components and hardware are structurally sound and secure.

Step 1
Prepare the 5th wheel head unit for installation by locating the hardware package containing four M14 hex bolts and flat washers.
The 5th wheel legs are compatible with 30K 5th wheel heads.
Step 2
Select a set of mounting holes that will allow sufficient clearance between the 5th wheel trailer and the sides of the tow vehicle.
Begin assembling the legs to the 5th wheel hitch head using the M14 bolts and M14 washers (provided with the 5th wheel head unit)
through the selected mounting holes and loosely secure them with the nylock nuts (provided in the 5th wheel head unit).
Note: Position the leg assembly with the operating instruction label on the driver side of the tow vehicle.
The large locking feet on the Ram 5th wheel legs will match the large rear mounts in the truck bed.

Step 3
With the legs in position, locate the cross
support weldment (#3). Loosely attach the
cross support between the two leg assemblies
(#1, #2) with the provided M14 hex bolts (#4),
and flat washers (#5).
Note: For easier install the pin and head can be
removed while installing into bed of truck.
Step 4
Remove the four lynch pins securing the
locking handles to the legs. Swing all four
handles completely open and lower the legs
into position in the bed of the truck.
Ensure all four locking bolts and spacers
drop into the mounting holes before
attempting to close the handles.
Step 5
With the 5th wheel legs in position, torque all eight
M14 bolts to 100 ft-lbs. Re-install the 5th wheel
head if it was removed to ease installation.
Step 7
Confirm all four locking bolts are engaged in the truck bed mounts
and the castle nuts are secured with the cotter pins. Double check to
ensure all four handles are securely locked with the lynch pins. The
5th wheel legs are now installed and ready for use.
Step 6
With the legs secured and positioned in truck bed mounts, rotate
the handles back to the closed position. Secure the handles by re-
inserting all four lynch pins. Note: Slight resistance should be felt
as the handles are rotated closed. If the handle will not close with
moderate pressure, adjustments must be made to the locking T-bolt;
see 'T-bolt Adjustment'.
WARNING
Forcing the handle closed may damage the locking bolt
and handle, possibly resulting in trailer detachment.
T-Bolt Adjustment
The locking T-bolts are pre-installed to ease installation. Due
to possible variation in the truck's mounting locations, some
adjustments may be required. If one or more of the locking handles
will not close, begin adjustment by removing the cotter pin securing
the castle nut above the handle. See figure below.
Next, loosen the castle nut 1/4-turn while pressing down on the
T-bolt. Reattempt to close the locking handle. If the handle closes,
re-secure the castle nut with the removed cotter pin. If the handle
does not close, loosen the castle nut 1/4-turn while pressing down
on the T-bolt and reattempt to close the locking handle.
