We have a 2010 Sunseeker 3120 Class C. Bought it used in 2013 and this is our 4th camping season. I always winterize with antifreeze and am very careful to make sure I get that stuff everywhere!
This weekend, we are FINALLY on our first of the season shakedown, after a tree fell on our RV back in April (all repairs were done). Last weekend, we slept out in the driveway with the kids, and I had to turn the pump off because it kept burping. I figured it was my leaky outdoor shower, although subsequent checks of it and every other area of obvious leakage showed nothing.
Tonight, as I was getting ready to shower, I blamed the kids for spilling water at the edge of the rug at the bathroom door. I sopped it up and thought that was the end of it. Well, lo and behold when I got out of the shower and opened the door, the spot is back
I went outside and discovered water leaking from the undercarriage, in an area that's been sealed by that spray-on stuff. It's running down the axle and dripping pretty good. It looks like a line that maybe goes to the kitchen sink, but I can't tell.
Anyone had this happen, where there's a leak you see outside your rig that bubbles up inside? The city water is off tonight and we will probably be cutting our trip short. I only hope we can get it fixed before our big trek down south in July. The little trips in between we can cancel (begrudgingly!). I wonder if it's fresh water or gray - I don't want to put dye in it, as it is coming up through the floor.
