I posted a message a few days ago regarding the fridge in our Outback 325bh not working on gas when the slide is in. I did some investigating while camping this past weekend & sure enough when slide goes in the gas supply line gets kinked. My new question is has anyone else had this problem & what's the best solution? Also where can I fine a new hose, upon checking mine it is starting to crack where it's kinked. I have attached a few pictures to show my setup. Thanks in advance
