Sorry to hear Jack. I can't reiterate enough! The 259 slide is big! 10 feet long and if the rig isn't dam near exactly LEVEL that big hole will be out of square causing your issue. You can't rely on the auto level! I installed bubble levels to assure I'm level before opening the slide. I level the trailer side to side before I unhook from the truck using legos under the wheels. If you don't do this the frame will twist. The auto level will try it's best but it can't handle with only a 4 point leveling system. Since I've been doing this I've not had a problem. 19 trips out since the repair. I learned this on my second trip after the fix. When I use the auto level it's level according to the bubbles about 75% of the time. You could upgrade to a Vroom but that's all I can recommend.
