Total Frustation

We spent the last 2 and half days in Iowa at a ruck stop. We get up this morning have a breakfast buffet at a near by casino (which was really good). We made in back to the shop just before noon to see if we could do our laundry here cause it is free at the shop. We were getting out of the truck when the apu starts acting up again. Doing the same thing it did when we got the truck. We spent four hours not even a week ago in the outside in the heat at thermo king cause they do not allow dogs in the drivers lounge, They replaced the motherboard on the apu but it is still doing the same thing again. It seems like nothing is going right.
