@grassgd, I did take some pictures of new Rhomar fluid compared to the 2 year old Rhomar fluid I drained and pH test strips on both samples. The top pH strip is old, bottom pH strip is new. It is hard to see much difference in the pictures but the old looks to be closer to 9 while the new looks to be closer to an 8. The old Rhomar fluid is definitely not as clear as the new
@Maple_Geek I'm guessing that all the expansion tanks have the aluminum sleeves that @Freespirit pictured above. Would it be possible to look into the tank and see if you have similar corrosion?
Trying a little experiment. I just put two strips of aluminum in separate glasses of glycol. One with fresh Century and the other with fresh Rhomar. It will be interesting to see if there are any differences in corrosion over the next months or years.
@AnOldUR my expansion tank is annoyingly located behind the cassette toilet in the small bathroom and is not at all easy to reach. When I finally find some time to do this operation I'll see if there is a way to remove it and look.
So I found one of the two reported bleeder valves in my 23 400. The rear passenger side one. The front dinette passenger side was no where to be found. Possibly under portal window if you take off the side panel to the left of the door as you’re looking at it from inside.
I just came across this January 9, 2019 video posted by "The Air Force Guy" describing the T@B 320 construction process. I may be wrong, but I do not believe it has been posted on this forum previously. From my perspective, it provides a much clearer visual description of how the 320 is assembled, including the roof and sidewalls. For example, I had not previously seen the foam inserts they place between the roof framing, or the aluminum foil type liner they add between the roof framing and the aluminum roof (starting around 4:19 in the video). I am now curious if my 2019 320 S (built in 2018) has that aluminum liner, or if that is something nüCamp has recently added. When combined with his previous 320 construction video, you get a pretty good idea of how the camper is put together. (Greg)
Here is a January 7, 2019 video on the construction of the T@B 400 which I have not previously seen as well. I apologize if these videos have already been posted. (Greg)
Regarding your extra Zamp panels, if you have been using them, they must have a Zamp charge controller built in, so, just use the alligator clips directly on the battery terminals. Both solar sources will charge the battery. The Victron charge controller will read the battery voltage, but only give you info regarding the installed solar panels.
Ok, thanks for the feedback I guess I'll add this dubious mod to the one where I found 5 batts of fiberglass house insulation stuffed around the tanks under the belly pan when I was fixing a greywater leak (I also found an 18 watt heating pad stuck to both the fresh and grey water tanks hooked via household wiring to the positive terminal of the victron solar).
I took the very gnarly looking filter element out & just left the clear housing in place so I can check for the white chunks floating through the system. I wondered why the radiators took so long to heat up when I first ran the heater, I thought that was normal.
