Ok, here is my stupid question for the day. Sorry for the length.
We have a 2017 Eagle ordered with the residential refrigerator/1000w inverter option. We will also be hooked up to shore/TV power almost exclusively so battery "requirements" really didn't concern me a whole lot prior to ordering. But then I got to thinking afterwards that in the event of a TV breakdown, power outage, etc. where shore/TV/generator power wouldn't be readily available, how long could the refrigerator operate on batteries alone? I have read a lot about this since we placed our order and now have a pretty good idea what will be needed to get an "acceptable" battery runtime, but wanted to get Jayco's input on this as well. So I talked with a Jayco sales rep.
Seems Jayco tested the residential refrigerator setup in my 2017 Eagle model at the factory using 2 -12v batteries (size/type not specified in the discussion), the refrigerator was "pre cooled" and stocked with cold/frozen foods before the runtime test started. The results were that the refrigerator was able to operate properly for approx. 16 hours but that Jayco was going to go with a more conservative 12 hours runtime for their "specs". He had no info on if that timeframe was at full or some percentage (50 percent?) of battery discharge nor could he give me specs on the batteries used other than they were 12v deep cycle. So as a customer, I would expect that our new trailer would come with a 2 battery setup of some kind since that is what Jayco tested with. From what I have read, that should be sufficient for our situation.
Fast forward to a conversation with our salesman a few weeks later about what BATTERIES (note the plural spelling) would be installed in our new trailer seeing we had the residential refrigerator option? I was told that they were only going to install 1 - 12v Interstate "RV" battery (again, no size/type) like they do with any other TT of that size, regardless of options. I found that very interesting to say the least and confusing at the same time.
If one 12v battery was sufficient, I would think that Jayco would test it with one, not two and base their numbers accordingly, but that does not seem to be the case. I would also think that Jayco would have at least some minimal expectation that their dealers are selling their products "as tested" to ensure some level of minimal performance but I guess not.
Stupid Question - Why would Jayco allow dealers to sell a product of theirs with a battery setup on a given RV build that was inconsistent with the setup tested by Jayco to produce their "numbers"?
I think I know the answer, but go ahead and beat me over the head with this dumb question. I probably deserve it.
