It seems like a lot of people have had this issue, us included. We did the mod that Lloyd suggested in this thread http://www.crossroadsowners.com/foru...ssue-8423.html
and now our tank gauge reads empty when we really are. Before we would run out of water and the gauge would still read 1/3rd. We have gained at least another day if not 2 when using our water tank.
When I did the mod I didn't remove the tank I just dropped the under belly. I had enough room to get the new pick-up into the tank but it was tight.
