TAB 400 BOONDOCK 2021 WINTERIZING
After consulting NuCamp, Nautilus, and You Tube, I think I have condensed the previously confusing process of Winterizing this RV. There were vast differences from the 2020 model while, the 2021 directions have not yet been released.
I hope this makes it much easier for the next TAB 400 2021 Winterizer.
Drain Fresh Water Tank
Turn Water Pump on & open all Hot & Cold faucets & Outside Shower lines. Do these (one line at a time). When water flow stops turn pump off.
Open Low Point Drain Valves, Hot & Cold (one at a time) & close back up.
Open ALDE Pressure Relief Valves (2 and they are yellow) One is for the Hot Water Tank & one for the ALDE flow. I have provided a photo below for one line. The other is there, but not in the photo. Easy to locate under the right side of the bed.
Drain Waste Water System. Black first, then Grey.
Set Nautilus to Winterization Mode. Make sure Red Lever is Correct! This is the ALDE Bypass Valve.
Connect short hose to City Water Inlet. Insert other end into Antifreeze Jug. Open kitchen faucet & turn water pump ON. You can use either the inside or Outside Water Pump Switch. Pump winterizing fluid into each Hot & Cold Line (one at a time) until pink antifreeze appears. Pump the fluid through everything that emits water.
Final: Pour ¼ gallon into every drain & toilet. ½ gallon into shower drain.
Please peruse these procedures and let me know if I need to edit. I would certainly appreciate your comments and I’m sure all TAB 400 Boondock 2021 owners will benefit from our effort.
