INSTALLATION
NOTE : Camper manufacturer must insure camper side walls are sufficiently
reinforced at corners for mounting jacks.
1. Bolt together flat and formed pieces of each corner bracket using
3/8˝ x 1˝ grade 5 bolts, flat washers and bolt retainers (supplied) as
shown in
FIG 1 or 4. Bolts must extend from the formed piece
through the flat piece.
2. Position brackets on corners so that jack will be perpendicular to
ground when camper is level. (See FIG 3) On rear corners with a
lower support bracket, place it at least 12˝ below main corner brack-
et. See
FIG 3-A.
3. On all corner brackets and lower support brackets, drive 1/4˝ diame-
ter lag screws (not supplied) into camper’s corner through center of
each slotted hole into camper framework. Minimum length of lag
screw must be 1-1/4˝. See
FIG 2-A for wide brackets and FIG 5-A for
narrow brackets.
NOTE : Holes are slotted to allow brackets to tighten up to the camper’s
corners as installation is made. Positioning lag screws in center
of slots permits bracket to shift without affecting the integrity of
the corner.
4. On wide brackets, use steel angles (not supplied) on inside of
camper’s corners to provide sufficient support. See FIG 2-B. Use four
(4) 3/8˝ bolts, lock washers and nuts (not supplied) to bolt through
each wide corner bracket, side wall and steel angle. Torque bolts to
15-20 ft. lbs.
5. Mount jacks to 3/8˝ x 1˝ long grade 5 hex bolts protruding from cor-
ner brackets (installed in STEP 1 above). Use flat washers and lock-
nuts ( SUPPLIED ) to retain jack. Torque to 15-20 ft. lbs. See FIG 2-C for
wide and 5-B for narrow (bolt retainer not shown for clarity).
NOTE : Jack must be located so handle clears all obstructions when
cranked.
NOTE : For trucks with dual rear wheels, use Swing-Out Brackets to
allow the front jacks to swing out to a wider position to clear dual
wheel fenders. Follow Swing-Out Bracket instructions MPD
87904 for proper installation and safe use.
6. For rear jacks with lower clamps, carefully spread clamps far
enough to slip over rear jack tube. Push onto jack and attach to
lower support brackets with 3/8˝ x 1˝ long, grade 5 hex bolts, flat
washers, and locknuts provided. Torque bolts to 15-20 foot lbs.

by the rear view in FIG 9 with 4-wire connectors on driver side and 2-
wire connectors on passenger side of camper. Receptacles must be
mounted within 5˝ from edge of camper, see
FIG 9-A.
8. Make electrical connections as shown in FIG 10 with front and back
jacks on separate 30 amps circuits with fuses located within 18˝ of
battery. Use 10 gauge stranded copper wire. Wiring must met RVIA
codes.
