I looked up pictures of the rear door of your 2015 Lance travel trailer toy hauler model 2212 and it appears to use a ramp spring like the part # RS16933LH and # RS16933RH which fits on a shaft diameter of 1-1/2 inch. You would need to measure the shaft of your setup now to determine if it would work. We've also found it will fit on 1-1/4 inch shafts too.
We do not have replacement doors at this time. view full answer...
