We finally just gave up and came home. The frig was getting worse, we travel about 200 miles when we move and the temps while on gas would start climbing as soon as it was switched. We stop several times so the dog can take in the sights, usually about and hour in and by then the temps are in the high 40's. The second stop will find it in the 50's, by the time we parked Sunday it was getting near to 60. Just got tired of fighting a cooler/ice and wasting food. Before I take it in I am going to test and record what it does. At the moment it is running on electric and the frig temp is 31, tomorrow I will switch it to gas and record the temps at regular intervals to see how fast the temps climb.
