Our Residential Refer doesn't seem to need any special care and feeding. This is the first coach we've had with Residential Appliances, to my surprize things remain cold while traveling down the road with no issues. I guess the only thing you should concern yourself with is whether or not you have adequate enough frosty beverages or steaks to fill that beast
We have had ours for a very short time and so far, very pleased. We have only travelled once and did have the doors and drawer open. We have looked into latches to keep it closed but what caught our eye, was a simple sheet of ply, cut in an upside down U, so it would fit through the door handles and extend down to hold the freezer in place. Looks like a simple design so I plan on giving it a try.
