Congrats on your new 180! We have a 2018 180 and absolutely love it.
We have a 2011 Tacoma PreRunner V6 and it tows the pod very well. I added an Equalizer 600/6000 WDH that also has excellent sway control. It was a night and day difference from the standard ball hitch. (With the standard hitch I could feel the trailer 'sashaying' from side to side on the highway, and the tongue bounced quite a bit when going over bridges on the interstate. All that was cured with the Equalizer.)
There is a thread here somewhere that lists rPod essentials that is good to read.
I agree with previous posters; Amazon / Camping World / Etrailer can get you far better deals than the RV dealer. If you are planning on doing a lot of dry camping (without 110 volt hookups) the dual 6 volt battery system is a good idea. It gives you a lot of additional capacity, but adds weight to the tongue. I upgraded to a group 27 marine battery instead of the group 24 that the Pod came with from the dealer. I had to only pay the difference in price.
You need a good trailer brake controller that will plug into the wiring of your Tacoma. They are about $100 or so. I had the dealer install it for me and set it up. I have a 'Draw Tite' with a digital display. Everyone has their favorite brands but they all seem to work the same. The harder you apply the brake the more signal it sends to the electric trailer brakes. The numbers on the display show how much pressure you are applying. The controller has two settings; one that determines how hard the brakes will grab, and the other setting is for how the brakes release.
You will need a good water hose with a pressure regulator, and a good sewer hose with a support. You will also need chemical for the toilet. (Put one packet of chemical into the toilet with a little bit of water to start. If you have sewer hookups the gray tank [sink, shower] can be left open to drain but the black tank should only be opened when you are ready to dump it and flush it out.)
Good luck. There are a lot of knowledgable people here that can answer just about any question.
