Just got back from a 500 mile round trip and wanted to report on something you might find useful. I like to keep an eye on the fridge interior temp. They often fluctuate quite a bit on an rv fridge depending on outside air temps. I got an outdoor/indoor wireless thermometer at Walmart for 9.99 last week and had a chance to try it out on this trip. I put the sending unit inside the fridge. The wireless feature worked so well that I was able to put the receiving unit in our tow vehicle and monitor the fridge temp as we traveled. The unit requires two aaa batteries in both the sending and receiving units. I have no idea how long they last but they were still going strong after four days of use. Both units are quite small. After arriving at the rv park we moved the receiving unit into the trailer so we could monitor both the temps of the trailer and the fridge. We ran the fridge on propane exclusively. The fridge did great usually holding a temp of about 34 at a medium setting (about 3 or 4 on the dial. The warmest it got was 40 and it was often at 32.9. We were very pleased with the fridge's performance. We had some frozen vegetables in the freezer section and they stayed very frozen. If you are looking for an inexpensive way to keep check on your fridge's perfomance without having to open the door and lose all that cold air your worked so hard to get you might try on of these.

I did use some aluminum tape to seal up some of the openings and make the air flow correctly and made a small air flow director out of aluminum flashing to make sure the air flow was right over the fridge cooling coils. Not sure how much all this helped. Also put two half gallon milk cartons of frozen water in the fridge before I started cooling it the night befor our departure. I left the frozen milk jugs in the fridge for the entire four day trip. There was still some ice in the milk cartons when we unpacked. They fit neatly into the fridge door. I had thought about installing a small computer fan to aid air flow over the fridge cooling coils (outside the fridge accessible through the upper fridge vent) but the baffle seemed to do the job nicely. We also used one of those very small fans powered by two d cells inside the fridge to make sure the cold air got circulated within the fridge.

After doing a baffle mod on several of the popup trailers we have owned I was really surprised at how good the stock baffling was on the KZ fridge. Being a tinkerer at heart I couldn't resist getting some alluminum tape to make it just a little better and keep warm air from being trapped. Sorry I can't offer a before and after comparison. I suspect that I did little to improve the fridge but it did work extremely well.

Hope this helps someone,
