2015 Outback Terrain water line freeze

[Sniperchad]

Hi all. Looking for any help. My outback terrain travel trailer is an “all season” trailer. In Colorado last week hunting. Dry camping. Got down to 17 and 19 degrees 2 different nights. The hot water line froze. Heater set at 60. Ran a lot of the night. Shouldn’t it be able to get a little colder before freezing? Doesn’t seem to freeze if above 24 or 25.
Suggestions? Didn’t really want to pull the under belly all off to investigate but may have to.
Thanks

Chad

Where did the hot water line freeze? Perhaps a setting of 60º is too low to get heat to all the parts of the system. Maybe leaving cabinet or closet doors open would aid in getting heat into those spaces. I think you're going to have to check underneath and see if more insulation is needed.

Don’t know exactly where the line froze. Haven’t dug into it yet. Closer to hot water heater tho as all hot water lines to the 3 faucets were froze.
Cabinets were all left open.
I will probably have to take off underbelly and see what’s up. I was hoping someone would have that magical wand same experience and maybe there was an easy fix. [emoji51]
