My T@B was lit up at night as almost nothing was completely off. I ran everything to this switch panel I added next to the Jensen in my '21 320. Now nothing glows at night. (L to R): Outside USB ports (I added), Inside USB ports, Jensen Stereo, TV, Blu-Ray/DVD player. I replaced the round ceiling and bathroom lights that glowed even when off with these dimmable exact replacements that are off when switched off: https://amzn.to/3XWh7HG
If you're using a mobile phone or other portable device, you won't see the whole URL that includes the model year and that may be your issue and frustration. You should actually start here https://nucamprv.com/preceding-models and choose exactly what year and model you're looking for. Choose Specifications when you get to the page. The year isn't prominently displayed, but you know it's correct because you've chosen the desired year and link.
Thank you Sharon is SAM and Binghi! I made what is likely a typical noob assumption that the pump is needed to move water through the water lines, no matter whether the source is the fresh water tank or city water. Having disconnected city water and set the Nautilus to dry camping mode, I find that the pump works perfectly as it should. I'm set for the moment until I encounter the next noob situation.
I'm with you on the suspension, rubber torsion axles are probably the worst for going down rough roads. The Dexter specs list a whopping 1.5" of up travel for an axle at load capacity. One of the hurdles when replacing the axle is that the tube serves as a cross member so you can't just remove it. Either build a replacement cross member or pull the swing arms out of the tube. Leaf springs aren't necessarily bad if they are designed for a good ride (long mono leafs or similar) but the typical trailer leaf springs aren't gonna cut it. I've been toying with the idea of coil overs which are pretty compact but do need a way of locating the axle with trailing arms or similar. Maybe next winter I'll brush up on my non-existing welding skills ....
Leaf springs would be my last choice. I’m surprised it was that bouncy. After having owned a tent trailer with leaf springs towing the 400 is a dream. The more overland-ready campers use coil springs and shocks but I have no idea if that could even be retrofitted.
