Trailer axle and gross weight ratings will be printed/stamped on a tag, usually near the front/left area of the coach or hitch box. The published unloaded weight declaration for RV's are very rarely accurate. They are based on a bare unit, and don't normally include accessories or upgrades (generator, batteries, dual A/C, satellite dish, etc.), even if you purchased it with the equipment.

If any of these are overweight, it's overweight. If so, you'll have to adjust the weight distribution, or lighten it up.
