After much deliberation, I decided to get both. A small Dometic 25 Top Loading fridge / freezer for the cab of the truck and a TruckFridge 130 to replace the icebox in the FWC. I attempted to take pictures the whole way through installation; however, once I inserted the card in the computer, there was nothing to download. I must have corrupted it someway. In anycase, I'll try and describe what I did and see if I can edit this later and re-insert pics.
Removal of the icebox was pretty easy. Remove 4 screws and pull out the drain tube. After that, you'll need to remove and discard the drawer above it and the entire face of the cabinet. You're going to have to remove all of the drawer support pieces. In my FWC, I used a square head bit.
The directions state that you should make sure that the fridge / freezer is upright for a minimum of 4 hours before powering up the fridge. Mine was upright the whole time I had it, so I figured i was good to go. I tried to dry fit the fridge and then realized that the tolerances on the side were fairly tight. I had to remove the top screw of the L brackets so that the side of the fridge would fit in the opening. I also had to remove the lower screw for the L brackets that held the counter top in place.
FWC pre-wires the area for a fridge which is incredibly convenient, so I tested the power on the wires and then connected them with the supplied coupling.
I still need to figure out a good way to ensure that the fridge does NOT slide out, but its difficult to move as it is, It may not move at all.
The Blue LED coloring looks kinda disco in my camper, but I think its kinda neat that it doesn't kill your night vision when looking for the cookies you hid from your kids.
All in all, it went together well and I spent probably and hour or so on this... So far a worthwhile modification.
