Speaking of the Dometic
fridge door, (aka like your
Casita has, and any other Dometic
fridge doors wherever they're installed,) I would also highly recommend the addition of door hinge supports, which just screw onto the existing door and over the hinge. If your fridge door hinge cracks and falls off, you will be out some major bucks to replace the door. You can pre-emt that from happening, or even repair one that the hinge has been broken on, by installing one of these. (I actually installed one on both the top and bottom hinges, but at least buy one and install it on the top hinge.)

FRIDGE HINGE REPAIR/DAMAGE PREVENTION KIT
All too often we hear of the top hinge breaking on the 17-foot Dometic fridges. This is bad news when it happens because that top hinge is part of that quite expensive door! This stainless steel bracket is easy to install and will repair that broken hinge permanently or prevent it from happening on one that's not yet broken! The very thin profile is nearly invisible when installed. This is a must have for all 17' refrigerators.
