I have been reading about others having freezing problems so I looked in the underbelly of my toyhauler.
I have a 2016 380TH. I don't know if all the Grand Designs are the same, but I found this today in the storage bay behind the removable wall.
The 2" vent pipe going to the plumbing station has a bad kink in the flexible venting. ---See arrow---

The fix was to reroute the vents to different ports in the main furnace plenum.

I found another kink in a bit further.

The fix was to disconnect the venting from the plenum and reroute it through the triangle gusset to the right. It might have taken 2 minutes and gives a better flow to the venting.

Mod Edit: Please do not post photos larger then 800x wide as it skews the forum for other readers. Thanks.
