Wiring is a real pet peeve of mine. Having lost our break lights and left turn signal a few hundred miles from the dealer on our new TM didn't add to the happy camper feeling. After looking the wiring over and doing a temporary fix, here is what I did in the refrig compartment. The attached pics will show the before and after.
The 2720SL has several cable runs that connect in the refrig compartment. Both shells. the TV connection, and wiring to from the converter. All splices left a lot to be desired IMO.

My fix:
Since most wires are labeled keeping track wasn't to much of a problem.
1. If your wires aren't marked do that first, masking tap works good.

2. Strip insulation off a wire so it seats properly in your connector, I used ring lugs so that will require removal of about 1/2 inch.

3. Twist the strands together in a clockwise direction. Tin the wires using a good 60/40 electronic solder with a rosin core.
DONOT use acid core. To tin the wires use a 100 to 140 watt soldering iron or gun. Place the tip on one side of the wire and the solder on the opposite side from the gun or iron. This draws the solder through the strands. Some kind of third device will help here. Caution things get hot here. Finished tinning on wire should be shinny. If not your temp. wasn't hot enough.

4. Crimp your ring lug ( or non-insulated butt splice connector) to the wire. You have just a little wire showing or bottomed out in the butt connector. Use the proper crimper for the connectors you are using.

5. Solder your wire to the lug or butt splice again heating on one side and drawing the solder from the other. For butt connectors make sure your heat shrink tubing is on the wire and well away from your soldering first.

6. If using ring lugs this means using a terminal strip. The type I used has a barrier between screws. After my wiring was done I used 3 inch angle brackets to hold the terminal strip to the floor. You may want to use star washer under the screws for a better connection. Also you may want a corrision inhibitor.
