Re: Fuses
@Sebastian, do you have a question? Turn the big battery disconnect to Off, pull out the fuse, and push a new one in. The fact it was connected to AC is not real relevant, the converter turns that into 12v DC for the TV and radio.
Re: Alternative weight distribution for 2021 T@B 400 BD
Hi,
When I moved up from a 320 to a 360 with my Jeep Grand Cherokee (full tow package/7200 lbs) I looked extensively into a need for a WDH. My research told me about the 5K pound rule of thumb, but I aso found it can beneficial with tow vehicles with short wheel bases (such as JGC) and /or if the total trailer weight is more than 1/2 of the weight of the tow vehicle.
The reason for this is a WDH has very little to do with sway (althought it does provide a side benefit) but rather it does what the name says and redistributes the weight on the tow vehicle from the rear of the tow vehicle to the front.
What happens, if the combo is not correct and you are getting a pull down in the rear of the tow vehicle to the point where it removes the designed weight off the front wheels, which leads to poor contact of the front wheels on the ground resulting in driving issues, most likely in wet or snowy conditions. The photo below is a bit extreme, but gets the point across. It essentially "levels" the tow vehicle back to front. It is more often not visable to the eye.
When I went to pick our 360 up, I talked to our dealer who only sells small trailers and he highly recommended it which "sealed the deal" for me in getting one (which he installed while I picked up the 360) I also talked to other "trailer experts". I checked on a bunch of JGC forums and they also agreed it would be of benefit.
I went with the Anderson WDH which does not use a tension bar, but chains. It is very easy to get on/off. Takes about an additional 2-3 minutes with no tools needed. Weight Distribution Hitch w/ Sway Control | Andersen Hitches
It's the same debate for the use of a sway bar...you think you will never need it, but there may be that one set of road/tow conditions that the added safety device will be of benefit. There is no harm, other than if your tow vehicle prohibits the use (you should look at your specific vehicle and not generalize) and it will provide better driveability and peace of mind.
Drive/Tow On!

Re: Confirming converter wiring
I'm not an electrician but as I understand it is frowned upon to have multiple ground to neutral connections. Typically ground and neutral are connected in the main panel, if there is another connection between the two the ground wire may carry part of the current that should only be in the neutral wire.
The converter is wired right after the main breaker in the power center, no idea what these red wired connect to. I'd open up the power center, remove the old converter and connect the new one the same way as the old one.
Re: Litime 320 ah mini lithium battery for 2021 Tab 400 Boondock
We installed a 300ah Renogy Core Mini lithium battery in the compartment where the two Harris AGM 6V batteries were located. Replaced the WFCO converter with a Progressive Dynamics PD4655V converter set to lithium mode. Installed a bigger gauge cable between the converter and the battery to speed charging. Installed a SmartShunt to keep track of things.
Re: Battery charger advice
Don't waste your money on a smart charger, RV LiFePo batteries don't require different stages of charging. The ubiquitous LiFePo chargers are simple constant voltage power supplies at 14.4-14.6 V. Personally I don't even use a dedicated LifePo charger but an adjustable lab power supply set to 14.4V .
Edit re alligator clips: These clips can have less than ideal contact and high resistance can lead to heat, especially with higher power chargers. You don't want to emulate Battleborn ....

Re: TAG 320 lithium battery conversion
The issue arises from how the DC-DC converter tries to reach the target output voltage. Say it is set to put out 10 A at 14.4 V, that is 144 W. If it receives 12 V from the tow vehicle it would try pull 12 A (ignoring losses for simplicity). So far so good but in most vehicles the wire run from the fuse box to the connector at the rear is fairly long so voltage drop raises its ugly head. The DC-DC converter tries to pull 12 A but if doing that drops the voltage to e.g. 11 V it now increases the current draw even further. Which in turn drops voltage even more (voltage drop is proportional to current) until either it reaches its lowest operating voltage or the fuse blows.eddycurrents said:Danke schön very much. This corroborates my existing bias. Re/ the fuse blowing issue, I presume you're talking about the excess load presented by the trailer, rather than the DC-DC converter's own internal circuitry, which I imagine would only add negligible current draw like any other switch-mode power supply..?
Re: Cordless drill for leveler jacks
Hi, if you use a drill with a variable torque setting , with a bit of experimenting, you can set it to the number that places the stabilizer foot just onto the ground , then the drill will go into free spin and not over torque or jump out of your hand. I bought a second drill body off eBay to keep in my TAB and set to the correct number.
Re: Soft Floor
The 360 should have the newer TransCore flooring. Believe if the bare floor surface (no vinyl pattern area, perhaps in the Alde compartment) has a white'ish color it is Transcore.
Transcore is not known to develop soft spots the way earlier nüCamp composite flooring like picture above @AnOldUR posted. Suggest you contact nüCamp Support to confirm your trailer's floor construction and discuss the softness you are observing - - don't work with a local RV Repair Shop until discussing with nüCamp.

If your curious what is under that floor this is a photo I took when I was repairing the black tank flush port on our 400. 
Re: Potential Battle Born Battery Issue
So glad I ditched the original BB battery that came stock in our 2024 400 , especially after hearing about the latest , ummmmm , findings .
When upgrading to more AH it was NOT a very hard decision to NOT spend over 1k for each 100ah BB battery to get more AH ! Incredibly over priced battery due to marketing and influencers !
BB claim to fame was the reliability and safety that their batteries had , Hmmmm , thats ironic !
For the cost of a single 100ah BB battery , I was able to upgrade to almost 1000ah for the same price (3 Dumfume 300ah batteries). Actually , the difference in price was almost a wash since I was able to sell the "new pullout, unused " BB for almost the cost of the 3 new "cheaper" 300ah Dumfumes .
BTW, the Dumfume 300ah batteries have been performing great , and more importantly are potentially safer than BB (have 6 of them in 2 different rv's ) , They are getting great reviews all over the internet . Even by WIll Prowse. Most people are finding that these are actually 314ah batteries after teardown.
Guess I am just glad I didnt "fall" for all the hype of the BB Batteries !
