Help I'm new to campers

I had to replace my fridge last weekend. Similar situation - went to precool the fridge on Wednesday and it wouldnt cool for a Friday trip. Found the ammonia evidence. Used a dorm fridge for the weekend until the replacement arrived. It really was a simple job to replace it. The three hardest things were: getting the old mounting screws out (one was in a stripped out hole so it would just spin in place rather than backing out, and one was at an angle that was difficult to get with a driver), getting the fridges through door (1/8 of an inch clearance with the fridge doors off), and last but not least -paying for the new fridge ($1,100 - ouch!). All is good now. If you decide to do this - remember on Dometic fridges the door panels are sold separately. Mine slide onto the door from the top down. My old ones fit perfectly, but I had to put them on the door before installing the fridge because the doors are close to the ceiling and there wasnt enough clearance above when the doors are on the mounted fridge.
