After several jammed slideout issues on my 2017 GT 270S and having to manually crank it in two times, finally figured out that the cable carrier was binding on some broken link pieces. It's still under warranty so my dealer ordered the parts from Forest River. After five weeks of my rig sitting at the dealers the parts finally arrived. Oh, FR sent the wrong size so it's been reordered. I'm sure that FR will Comp me the payments for the two months of not being able to use my rig.
I recommend caution for those guys patching the cable carriers. The broken link pieces jammed on mine to the point it tripped off the motor and it had to hand cranked in. Taking the molding apart to find the motor, playing contortionist to even reach the motor manual connection point and using a drill was NOT easy nor fun. FYI - As we all know the documentation is non-existent on many FR products, so if you haven't down loaded the manual slideout procedures do it before your next trip. When mine was jammed open, had to drive a couple hours out of the mountains to get a cell signal to down them before driving two hour back to the rig. I was NOT a happy camper that day.
