When we lost our American Coach due to a defective NorCold refrigerator, GMAC paid us what they thought the motorhome was worth in a "depressed economy". We were left holding the bag for almost $30,000 that was not covered (what we owed the bank and what the coach was worth). We were not aware of "gap" insurance when we purchased the coach, but I cannot stress how important it is. We would not be paying on a non-existant motorhome if we had had it at the time of loss. Now we are covered with gap insurance and would like to look in to full replacement, as even with gap insurance it is difficult to find the cash for another down payment.
By the way, even though NorCold was 100% to blame, they do not feel that they owe us anything other than what the GMAC paid!
