RR, ours had a similar problem and it went back to Spartan for that reason. It was that last overnight stay at LD that I said it needed to go back and be fixed right. LD had 30 days to correct it and they could not. I lost all air pressure on the rear gauge before bedtime after 3 attempts to fix the problem. Not sure what Spartan found yet until we pick up the coach next week.
