At almost 30 years of age, it is a good time to think about a whole new power chassis. A Progressive Dynamics PD-4045 is an excellent choice, it has AC distribution, a 45 amp converter, 12 Fused outputs for DC accessories and a 3 stage smart
battery charger.
I have installed about 7 of them in customers, as well as my own RV's, without problems. Less than $200 online.
