"If you are not towing it forget about."
Good advice. If you intend to start traveling with it, the axle will have to be addressed as Bill also mentioned. They are cheap to replace--I would replace rather than re-bend...if you ARE going to travel, might be best to replace the front also. Probably the most irritating problem with RVs stems from tire, axle and brake problems.
