The upgrades for this trailer include a new water heater, air conditioner, the new upholstery on the dinette couch and a new sofa couch inside the trailer. Extra items that are included are an RV power protection 30 amp weather resistant plug just in case of faulty park power that may happen. And a new shower head from the previous version we had.
