I have a 2014 3600 voltage. I bought this RV used. I started having water coming in bedroom wall. I found out that the front side exterior light fixture was warped due to heat from incorrect size of light bulb. The lense does not seal and water was getting inside lense and running in the 3/4" hole they drilled for the 2 small wires. I have looked everywhere for a replacement light fixture and cannot find the right size. The size is 11 3/4 x 5 3/4. Can anybody tell me where I can get one.
