We have a 1996 Winnebago Itasca Spirit 29RQ (Class C). We have replaced the cooling unit on our fridge 3 times and it is ready to be thrown out. We would like to replace it with a residential fridge. Has anyone found a good replacement with similar measurements (52-7/8" x 23.5" x 24"). The only one we can find is a Magic Chef 5.1 cu. foot fridge from Walmart, but it only comes in white. We would like either a black or silver replacement. Also, are there any other conversion concerns we need to be aware of, i.e., electrical...? Ann
