Hello,
We have probably the same setup on our FR Surveyor 220. Not needing the rack, I took it off and its in storage. I then mounted the spare tire, stock location under the chassis in the front, onto the back bumper, which made it easier to get to and saved tongue weight (although I suspect the weight of the rack and spare tire were probably very close and cancelled each other out). In any case, the spare tire is now easier to access and I don't have that heavy rack on the back that we don't use.
Happy Camping!
