Good info.. We will have to have more discussion about the 8 vs. 12 refrigerator. I know my wife has a serious hang up over cabinets. She can never have enough, and fills them up...with something. We usually pack a lot of food, a lot of frozen, and bring half of it back home.
If she can get on the couch and put her feet up she will be good.
Our old 1986 Class C was on a E350 chassis. No problems especially after I replaced the 35 gallon gas tank with a 55. Had the 460 with the last year of C6 transmission. Only thing I didn't like was the heat off the doghouse on my right leg. I assume the newer models have more hood and less doghouse. We need to go look at Jayco some time.
