Boy, you're a better sleuth than me! Can you provide a link to the instructions? Thanks Frank.
Ski try this. truckfridge.com/pdf/tb
I don't know now how I got into the pdf but went back into history and found the address.
Also I called them and asked about the model TB45 which opens front to back,that style has been discontinued.It wasn't popular.
I am going for the TF41,I was thinking to get the largest one but the fit might not work as well.The lid may not open enough,it might hit the inside of the roof.
I find it interesting that you just use an ice chest for your trips.We did that for years and got tired of finding ice.Now we are not big meat eaters so veggies keep well for camping,but there is a time that some chicken,fish or beef work for us.
Will keep posted and let you know when it comes.
Frank
