REMOVING BEDROOM SLIDE-OUT FROM RV

WARNING
WARNING: The next steps involve moving and removing the bedroom slide-out from the RV. EXTREME CAUTION
should be observed during this process to make sure the slide-out is properly braced and supported to prevent
it from falling. Have dollies or carts available to place the slide-out on once removed from the RV. Failure to do
so may cause death, serious personal injury, severe product and/or property damage if not performed safely and
within the parameters set forth in this document.

1. Remove the T-bracket on the outside bottom edge of the slide-out (Figure 1a and 1b).
2. Extend the slide-out room fully outward and support from below using a forklift (Figure 2).

3. Use a screw gun and a #2 square drive bit to remove all of the column screws including the four (4) fasteners
hidden behind the bulb seal on each side of the slide-out (Figure 3a and 3b).
4. Pull the interior portion of the column and wipe seal away from the wall. Locate the wires to the slide-out
drive motors. This wiring and connector will be located at the top of the slide-out sides . Pull apart the motor
connection (Figure 4a) and feed the motor end of the connector through the hole in the wipe seal (Figure
4b).

5. Remove screws from the outside of the slide mechanism column (Figure 5).
6. Use a razor knife to cut the sealant away between the vertical columns and the sidewall (Figure 6a), while
using a prying tool to pry the vertical columns away from the sidewalls (Figure 6b and 6c).

7. Prepare a cart, or a platform to set the slide-out on when it is removed from the RV (Figure 7 or similar).
8. Remove the slide-out from the RV. Gently lift the slide-out room in the opening. Tip it backwards (out at the
top) and rotate the wardrobe end outward to allow clearance for the lav cabinet (Figure 8a and 8b). Once the
top has cleared the opening in the wall, lift the slide-out enough to clear the lav cabinet over the lip in the
slide-out opening in the sidewall (Figure 8b). NOTE: Remove the room slowly, and be certain the wiring
and plumbing under the lav cabinet and wardrobe do not catch on anything as the room is lifted and
removed.
9. Remove the slide-out and place it on the cart and floor (Figure 9). Remove and clean all residual adhesive
from the slide-out columns.

11. Use a screw gun and a 1/4” socket to remove the 1/4” X 1.5” fasteners holding the lower wall brace in place
(Figure 11a).
12. Use the screw gun and a 3/8” socket to install 3/8” X 1.5” hex head lag bolts (P/N T110390) in place of the
original fasteners (Figure 11b and 11c). Tighten fasteners to tight - no torque spec.

+ NOTICE
If the bedroom slide-out has a composite floor, proceed to Step 1 on page 24 (Front Cap Removal). If the
bedroom slideout has a plywood floor, continue with Step 13 below for the procedure to replace the plywood
with a new composite floor. Do this ONLY if the bedroom slide-out has a plywood floor!

13. Prepare two wooden supports from 2”x 6” boards, approximately 4’ x 6” x 6” on the floor to rest the slide-out
box on, and cover top surfaces with styrofoam (or other soft material) to prevent damage to the exterior face
of the slide-out (Figure 12).
14. Remove the slide-out from the RV and place it on the floor, then rotate the slide-out room face down onto
the supports (Figure 13).

15. Remove the slide-out columns from the sides of the slide-out room (Figure 14) by sliding them out of
their mounting brackets. NOTE that there is a small plastic rivet that will break while trying to remove the
columns; this can be replaced during re-installation with another plastic rivet or a screw (not provided).
16. Using a screw gun and a #2 square drive bit, remove the fasteners holding the L-shaped bottom slide corners
from the slide-out box (Figure 15).

23. Lay new slide-out floor on supports with the interior side facing up. Lay pink insulation (P/N 101851)
over the floor and cut about an inch longer than the room. Peel the backing off of the adhesive on the pink
insulation and flip the insulation so the adhesive side is down (Figure 23).
24. Apply insulation to the floor and trim to fit (Figure 24).

Figure 23

Figure 24

25. Flip the floor over. Measure out the hole centers for the under slide lights (6” in from the outside face edge of
the floor and 18 ¼” in from the side edge of the floor) (Figure 25).
26. Use a power drill and a 3/8” spade drill bit to drill the holes for the LED lights (Figure 26).

27. Lift the new floor and set into place against the bottom of the slide room walls. The holes for the lights
should be near the outside face of the slide room and the pink insulation should be facing the ceiling of the
slide room (Figure 27).

29. Using a screw gun with a #2 bit, secure the bottom corners of the room to the floor with one (1) 14 X 1.5
ZINC (P/N 100883) screw in each outside corner (Figure 29).
30. Align the walls with the floor and ensure the slide room remains in square. Secure the other two corners of
the room with one (1) 14 X 1.5 ZINC (P/N 100883 - NOT provided) screw in each corner, then secure the
rest of the wall using at least four (4) of the same 14 X 1.5 ZINC screws per wall (Figure 30).

31. Once the side walls are secure, align the outside
wall and hold the removed T-Molding in place
and mark the screw locations in the T-Molding.
This will prevent from screwing the T-molding
into an already existing screw from the floor
(NOT shown).
32. Using a screw gun with a #2 square drive bit,
attach the floor to the outside wall with eight (8)
10 X 3 screws (P/N 100880) (Figure 31). There
should be a minimum of 8 screws through the
floor into the outside wall.

SEALANT

33. Using an oscillating multi tool with a chisel blade
(or equivalent), remove any old sealant along the
floor line of the slide-out (Figure 32).

Figure 32

34. Place Eternabond seal strips (P/N 102489 ) over the side wall to floor corners of the slide room. Trim them
around the T-molding. Make sure the strips completely cover the screw heads for the floor (Figures 33a and
33b).

WARNING
WARNING - Make sure the RV is unplugged from ALL power sources (including shore power) and all disconnects
are turned “OFF”. Failure to do so can result in death, serious personal injury, severe product and/or property
damage.

5. Use a screw gun with a #2 square drive bit to remove the four (4) screws holding the shore power cord
connector to the sidewall (Figure 23e).
6. Pull the shore power cord connector out of the sidewall: gently pull the cord attached to it out with the
connector (Figure 23f). Loosen the plastic nut (or compresion cap) on the back of the receptical to release
tension on the cord (Page 29, Figure 23h).
+ NOTICE
NOTICE - The power cord attached to the
back of the shore power cord connector is
anchored to RV structure with a P-clamp.
When pulling the cord out of the RV, you
may need to access that clamp to release
the cord to remove and reinstall the shore
power cord connector.
Access can be gained by loosening the
furnace and sliding it to the side in the
opening far enough to allow your arm to
reach behind the wall to reach the P-clamp
(Figure 23g).

+ NOTICE
NOTICE: The following steps involve removing the shore power cord connector wiring cover Brinkley uses
two (2) different types of these: installation and removal are virutally identical, but there are slight differences
in the way the back covers are removed that will affect how you access the wire connections.

The Furrion connector uses two screws that pass though the front connection opening to hold the rear
wiring cover in place (Figure 23h). Remove the two (2) screws with a HAND SCREWDRIVER with a #1
Phillips bit, then remove the plastic nut at the end of the back cover to relase tension on the wires.
Remove the back cover to access the wire connections.

The Epicord connector uses a “twist-lock” action to lock the rear wiring cover to the back of the connector
base (Figure 23k). Twist the compression cap at the end of the rear cover loose to relieve the tension on
the wires. Twist the rear cover counter-clockwise until it releases from the back of the power inlet and
