I also have the SSO rear bumper and experienced the same issue with the rear ladder. Kevin and Gwen at SSO are great people and wanted me to ship the ladder back for some re-work after seeing the pictures. I was able to come up with my own solution where I trimed a very slight wedge out of the bottom of the uprights, then added a shim between the ladder base and swing arm which pulled the ladder about 1/2" away from the hatch and fixed the issue. I just touched up my cuts with a little paint and rocked on. After a week in Death Valley towing a 2,000lb Turtleback it is still going strong.
SSO is growing by leaps and bounds and while it's not really an excuse, I applaud the guy who was just recently able to quit his full time job and make a go at his own business. He is working through man power, craftsmanship, and QC issues while trying to keep production rolling. I'm pretty sure the reason the bumper is now on hold or discontinued is so they can get control of the flaws in the system. Knowing this, and the lengths that they are willing to go to make things right, I have a lot of patience and want to see them succeed. He could still be taking orders and making money but made the right choice to reign it in until quality control can keep up.
Hang in there, they will make it right.
