One of my gas assist door opener/stabilizer has frozen up and needs to be replaced. I have a 2007 5th Wheel 3400RL Heartland Big Horn and the broken gas rod is located on the left front storage door where access to the basement and the water/satellite is obtained. The part number is Stabilus Inter-Stop 5769RF 0250N 248/6 A 2. I think the 250N is the pressurized nitrogen charge, and the 248/6 may be Julian date/year. I tried to search the internet for this part but no luck. Anyone have any info who might be a source for these stabilizers? I will also try Heartland tomorrow. Thanks. Joe
