So took my Campster
back to my favorite local RV shop along with a printout of comments posted here. They gladly reinstalled, at no cost to me. These guys have been super every step of our renovation. The Campster
is garage stored, so may be awhile before we are out in the rain for a test, but feel pretty good that the problem is solved. Thank y'all so much for your help!
AND if you are ever in the San Antonio/New Braunfels area, these guys on I-35 are the best!: Texas Hill Country Coach
