That 30 Amp rating is for household 120V wiring, where conductors are packed closely together, as in Romex cable. The 52 Amp rating is for individual wires which can dissipate heat more readily, which is what you've got. I stand by my statements. It's all very well suggesting that @WebTab2021 goes out and buys a specialized charger when they have a perfectly good charger already which just needs a little assistance, but some of us don't have money to burn.
We just got word that our 2024 T@B 320 CS-S is going into production next week. From what I understand the changes are interior wallpaper color, elm cabinets, and the galley design is changed. They are now using a 45L 12v slide in cooler instead of a built in fridge. Over the cooler is a removable cutting board which needs to be tilted in order to access the cooler (or you can just pull the cutting board out). I can post any other changes here. I think the only other minor change is that the door frame is black, not white. We have ordered ours with the Lithium package as well.
@DukeHewett, @jimcenname, and @otr_320, thanks for the input. I'll check out the Shurflo Pentair 4008, and possibly an accumulator.
I guess I can't complain too much. I gotten nine full seasons out of the pump (though certainly not full time), and at least it had the decency to die after my last trip of 2023! :-)
Another perspective. Our 2021 320 cannot be fully drained due to faulty factory installations of sagging tank, ineffective low points, and improper sloping of lines. No amount of compressed air can compensate.
So in goes four or more gallons of antifreeze after draining all lines and valves, pumping it up through systems, emptying ranks and priming drains with full strength mix.
Having wintered decades back in uninsulated cabins, learned the hard way that drained piping still has lots of water coating piping walls, which coalesces and freezes, cracking fittings at the hardest to solder spots.
I find it safer to use antifreeze and not wonder if you got all the water out of low points and valves.
Leaving in AM for two weeks in the 20s South through 60s North. Weird weather.
I've always used the antifreeze method without blowing anything out with no issues. I use prestone -100 antifreeze and our trailer is winterized from October to May with regular temps in the single to negative digits. Never had anything break over the winter.
Yep, same year T@B and pump failed with no warning within the last year. Might have been the pressure switch, but it wasn't worth the time trying to troubleshoot further. We just bought a replacement that was easy to accomplish. I may have had to mover the new one over or down just a tad, but it fit fine. Not sure where we got it, but you can Google: Pentair Shurflo 4008 RV Revolution By-Pass Pump. It has worked great and supposedly will not burn up if you run it dry. Under $70 on Amazon. Good Luck and "let it flow".
I live in a 2019 400, I use the pump and tank water exclusively. I've replaced pumps 3 times until I installed a Shurflo accumulator. Smoother operation and longer lasting service.
