I forgot to add that we're full-timing for a couple of months in our 3585SA, which we bought in late August. Also, the hot water, which wouldn't run an hour ago, is now running just fine. The only thing we've done since coming home is turn the furnace up to 70. Beats the heck out of us how we don't have water and then we get it (both times) within an hour or less. Well, I won't complain because we are back in business here on Horse Prairie, but I surely wish we could find out why the water freezes with the skirted rig and auxiliary heat underneath, and why the water begins to flow an hour or so after we get home. Thanks for the encouragement and hints--and keep them coming, because sooner or later someone will have the magic fix!
