The issue im having with my RoadTrek 170 ( Year 2000 ) built on a Dodge Ram 3/4 ton,, is that when i plug the camper in to AC it rapidly BOILS the cabin battery until it actually explodes.
I had the original one crack and the acid dripped out on the ground.. I replaced the alternator and battery isolater, same thing.
Then i was thinking that its fine when not plugged in SO it cant be those components..
Whatever it is it must be related to some charging system when plugged into AC only... any help appreciated
PS - im good with a meter and have tools..
Thank You in advance

Symptom of over charging. What is the battery voltage when plugged in? Should be about 14.4V for discharged battery down to 13.4V as it charges.

If the voltage is under 14.4 and excessively gassing there is probably a shorted cell in the battery. Time for a replacement battery.

Geez Why replace the alternator when the problem is with whatever charger/converter the RV uses to charge your battery when on shore power. Since you are still having the overcharge issue with a new battery I would think most likely the problem is with your shore powered charger unit. Find it, check it out and replace if necessary.

Your power converter is overcharging - that is a typical scenario with older converters.
We have a 170 on the Chevy chassis - I imagine it is similar. Our converter is under the driver's side of the back dinette cushion. There should be a vented door in front of it - probably brown. We replaced our converter with a Progressive Dynamics converter and we leave the van plugged in 24/7. It is a smart converter that changes the amount of charging so it won't boil the battery.
We used a PD4645 as a direct replacement for our old converter from BestConverter.com
Good luck.
