I called Lippert and spoke to one of their service techs. He was nice and has seen this problem before. He said if the problem persists he believes that it would either be the solenoid on the right jack or the jack itself. There is an internal O ring and if it is allowing the fluid to seep by it, it would cause the jack to slowly drop. I followed Jess' advice and raised and lowered the front jacks several times. I started for Mesa, Az from Lake Havasu and stopped and checked it quite often. It did not drop down at all! Much different than the day before where I had to stop and raise it up every 30 to 60 miles. I will continue to monitor it very closely. Of note I did find one of the red hydraulic lines that had a small amount of fluid seeping where the hose attached to the fitting. I will replace it very soon. I want to thank all of you for the great advice. I find the Heartland Owners Group to be very helpful when one of us has a problem.
