I want to add to my 12v system but where should I focus my attention and money? Collection or Storage? I have a 2022 T@b 400 BD I call the T@bacabana.
I have an external solar port that came originally from Nucamp that ties into the battery. Adding a suitcase solar array 100w or even 200w would give me more energy input to compensate for the PNW tall trees and overcast/rainy days. I would also have to check on the fuse amp and think I need a separate controller for it and get a 10' max cable.
I also want a battery monitor and I'm looking at the Victron BMV-712 bundled with a shunt; or maybe a smart shunt (700 or higher?). $$-$$$
For batteries I have the standard for 2022, 2 AGM 6 volt batteries with a Victron controller. The 2022 supposedly has a lithium switch that makes converting simple. Someday I want to upgrade to lithium batteries. $$$$
More solar means I can use the inverter more too plus keep the frig cold and crank up the fan during the day and use the lights at night.
I've been checking out the forums but does anyone know a good resource on configuring for a tab solar expansion so everything plays happily together?
Everyone in the forum seems to be finding solutions that work with their model and year but it can be confusing and contra indicative for someone new to 12V systems.

We have the stock 163 watt roof solar and if we are parked in the shade I will plug in either a 100 watt panel or add the second one for 200 watts. Never had a problem keeping the batteries topped off even with using the inverter to run the coffee pot in the morning. We do have the 3 way fridge that runs on propane so I'm sure that helps us a lot with our power consumption.
So if I were you I'd keep the batteries you currently have, you can change to lithium when their life finally runs out, add the victron smart shunt, and get a solar suitcase. I would either get a 200 watt suitcase or a 100 watt panel that has the ability to add a second 100 watt if needed. The suitcase needs it's own controller. You can also have a cable longer than 10 feet for the suitcase. But check with the specs of the suitcase. I have a 16 foot cable and will plan on getting a second 16 foot to my kit this summer. This is allowed in the specs of what I have. I already had two 100 watt jackery panels so I simply added a goal zero controller to them. A self contained suitcase is certainly a cleaner set up than what I have. However I really like having he ability to just hook up a single 100 watt panel or both of them. The panels are super lightweight and easy to carry around.

I already have two Yargo YP100 suitcase panels and will get two more to start with. The 150/35 will allow me to use up to 6 of those in series. In my opinion having the panels in series is the only way to go if starting from scratch. You will need much larger wire if you put them in parallel.

In our area suggest going with the shunt 1st, then a remote panel option, then update batteries when needed to what you find you need or 2nd after the shunt if you need more capacity. Remember whatever capacity you have unless sufficient for the trip can't be counted on to recharge if you are in low light most of the time. BUT with Lithium it will be faster than Lead acid. If going for longer than 3 days or expect sun I bring the remote panels - they strap to the carrier on the T@B & I pull them down if needed.
Camping on the east side and open areas I'm always amazed that I don't have to worry especially when I crank up the remote panels.

The Victron unit already in your trailer is for the roof top solar, and is the solar controller, not a battery monitor per se. So adding the 712 gives you full 12-VDC battery monitoring, and the Victron app can tell you not only the battery voltage, but is current rate of use and how long you have power left for at that rate of use.

Like many have already commented, I would start with an external panel first to supplement your rooftop solar. You may find that is all you need to keep the batteries topped off. Work from there taking into consideration your style of camping and your specific needs.
