Univolt upgrade for a 76 Argosy

I have redone a 1976 Argosy.
I have added 12 volt lights , replaced the fridge unit [now has a 12volt circuit to start the propane ignitor] and replaced the 3 vent fans This has resulted in more demands on my 12 volt system. Lights dim , fans slow, and the warning light on the fridge illuminates when using multiple circuits .
The univolt system is the original unit. The 12 volt panel is a main line 50 amp [ univolt / battery],followed by a 30 amp [main charged line ] , then 4 -20amp circuits .
Should the system be uo-graded to a 80 amp univolt ? Would this solve my problem ?
If not what would ?

Sounds more like a bad ground or corroded battery cables or a bad battery.

Replacing the Univolt is a good idea go with a 3 stage charge 55 amps should be plenty.

I replaced mine with a 65 amp Progressive Dynamics 9265 and real happy with it.
I kept the Univolt fuse panel.
