Hello,
We seem to have the same TC as you, a Camplite 10.0 2013. In the first post of this thread you mention a "top side vent" for your fridge. I am not sure we have a top side vent on our 2013 TC, we might have one side vent and one roof vent for the fridge. I will have to check that when I get home from work.
Anyways, we also have had the temps go way up inside the fridge when traveling, but that was when we drove 8-11 hours per day, and they went into the low 50's. It was summer and a lot of direct sun on the camper, so we thought nothing of it.
I am afraid I have not paid that much attention to the temps on all of the shorter trips we take. Perhaps I will after reading your postings. I do know that trying to use the DC setting is useless, our temps went way up as if nothing was on, so we never use that setting any more.
As with yours, ours works great when in camp, AC or gas, no problem.
Best of luck to you and I will keep reading your posts to see if there is anything I need to do to our fridge.
Take care,
Del
