Another question.......has anyone verified the level on their coach with a bubble level after leveling with the automatic jacks? I plugged my coach in last night in my driveway to get the fridge cold before a trip tomorrow, and I remembered at work today that I hadn't checked the level, and the jacks weren't down. So....when I came home today, I immediately went out and checked the level, and the left side was significantly lower than the right. I used two different bubble levels, manually raised the jacks on the left side, and the bubble was perfectly centered in the bottome of the fridge and the freezer, as well as the table & buffet. Before I did that, I even layed a can inside the fridge, and it immediately rolled from the back to the front. Afterwards, it didn't move at all! So........ obivously the jack sensor mechanism needs adjusting, and the manual tells you HOW, but it doesn't say where it's located. Anyone know?? I'm not sure I want to attempt to adjust it myself anyway, but I'm curious where it's located. :>) Thanks in advance for your replies.
