@TagURit, the 12V DC mode is intended to only be used when the camper is attached to a running tow vehicle. In this case, the vehicle's alternator provides the needed power. In theory, anyway--that was what @ChanW was referring to with regard to many modern vehicles not being able to keep up with the demand.
Once in camp, you would run the fridge off 120V AC (if available) or propane.
I also rarely use the 12V DC mode. When in transit, we find a pre-chilled fridge with couple jugs of ice in it does a fine job staying cold until we get to our destination. You need the ice for happy hour, anyway! ;-)
In my not-so-humble-opinion, 2015 was great model year. Larger tanks had been added mid-year and front windows were virtually standard. However, the race to add more and more "convenience" features had yet to start, so these models are still relatively simple and have fewer systems to give you headaches. You can always customize your own trailer to fit your needs, once you decide what those needs are.
After reading all the concerns about cooling the refrigerator while driving via 12v, I’m going to do the following: 1) pre-cool the refrigerator on AC before leaving, 2) Use Cooler shock ice packs and turn off refrigerator. Then at campsite 3) I will use the propane to power the refrigerator.
I understand for those on long trips, this might not be a solution.
Hello @sjanin and welcome! I have been through similar trials with my "new to me" 2014 T@B 320 S, which I purchased in Nov 2020. Once you get to know them, they are marvelous! I have felt over my head numerous times. I started out with short trips and learned one system at a time. This coming week, I'll be taking my longest trip yet and will be using the black tank for the first time! I have been learning that the T@B is tougher and smarter than I realize and has tolerated my many mistakes amazingly well. https://tab-rv.vanillacommunity.com/discussion/12574/dead-battery-2014-t-b-320-s#latest Assuming the battery that came with your 2015 is not new, depending on how the previous owner treated it, it might not be fully functioning or reliable. If it is the original 2015 battery, it is due for replacing. You might choose to: 1. get the battery tested to see if it is holding its charge correctly 2. replace it with another comparable battery 3. upgrade to a different type of battery, such as AGM or lithium. These are lower maintenance, dry cell batteries. 4. get a wireless battery monitor I upgraded to lithium because I almost only boondock and love to camp in the off-season. I have a fairly low cost solar panel suitcase, but to be honest, the lithium holds the charge so well, I haven't had to use it yet. I think the cost of the lithium is well worth the peace of mind and low maintenance. https://tab-rv.vanillacommunity.com/discussion/12623/lithium-battery#latest One other bit of advice - purchase all the fuses you might need, especially the tiny ones for the Alde! I've already blown mine once when I connected to house power without first turning the Alde off. https://tab-rv.vanillacommunity.com/discussion/3512/fuses-for-newbies/p1
