Went camping this past week and enroute I had a problem going up hill. My rv started to hiccup or so it felt and when we got to the top of the mountain it said to check transmission temperature. Our 8.1 will Allison does not have a temp gage that I am aware of. Had no further problems with it after that except it just did not seem to have th power it had before. Also while camping our water heater board went out again for the fourth time. This was the third time with a Dinosaur board. Could find no one in Utah that used Dinosaur so went back to the OEM board. Was told Dinosaurs are crap and yet in Arizona everyone swore by them. I went thru two Dinosaur boards in two month in Arizona. Go figure.
