I have the same camper. You have Dexter 3,500 lb axels. There were no serial numbers on ours ,just the Keystone order tag and lot number. If you replace the bent axel with the same axel you will wind up bending another one. The suspension is not heavy enough for the 7200 lb. GVWR. I weighed 6900 lbs when I bent ours on a I95 coming home from Disney World. I planed on keeping ours so I upgraded the springs and axels to 10,00 lbs. 5200 lb. axels, with 2500 lb. springs, and Dexter heavy duty shackels and wet bolts. Best mod I've made so far. This is an expensive upgrade so only consider it if you plan on keeping the trailer for a while.
