Me and my girlfriend bought a 1979 Dodge Sundowner/Swinger RV that has several problems, but the most is the battery. After replacing the belts, alternator, relay, and starter. I replaced the battery about four times and still doing the same thing. What part that I missed that needs replacing?

u need a multymeter(not expensive)disconnect battery-,connect meter set to read 0-10 amps between bat- and bat-clamp,meter will read the drain probably 2-5amps if bat drains fast.next remove fuses 1 at a time untill amps drain reads 0,this is the cuircit causing trouble.u then have to find every thing this cuircit feeds and test to find the fault and repair.given what u have replaced so far i suspect a light circuit staying live.most common are storage compartments with doors so u never notice the light stays on.finding faults is relativly easy if time consuming. just be methodical and watch the meter read out .the smallest of bulbs can drain a bat in24 hours or less
