Our Thetford fridge condensate drips via a small pipe into a small grey plastic container in the lower vent cavity, where it just overflows onto the vent cavity bottom. The chap in the next pitch has extended the pipe so it drizzles out of the vent slats. Both of ours. however, do have a decent sized drain at the bottom of the lower vent cavity (lower right of pic). Anyone know why the condensate pipe is not routed down there anyway in the first place / know why it shouldn't be?
