We bought a 2307C just over a year ago, aren't too far from you (Sacramento area). We also do a fair amount of dry camping, generally in state & county park campgrounds (usually quite a bit cheaper - and often quieter - than KOA's and other commercial RV parks with full hookups).
We found that even after adding a 2nd battery, we use more power than a solar panel can recharge (even with much of the interior lighting converted to LED's) so we bought a Honda 2200 watt generator last fall (and may get a 2nd companion unit if we find we really miss being able to use the a/c this summer).
Even with just two of us in the trailer, we find the gray tank fills up in about 2-3 days - since we tend to spend at least 3-4 days in one place, we picked up a 32 gallon Barker 4 wheel portable waste tank - lets us empty the holding tanks & tow the portable tank to the dump station without moving the trailer. https://www.amazon.com/Barker-27844-.../dp/B000BGM89Y
We also bought a small "table-top" stainless steel propane bbq (small enough to store under one of the dinette seats) so we don't have to rely on campground bbq grills (https://www.ebay.com/itm/Nexgrill-2-...-/163175844083
). Didn't want to have to carry a separate full size propane tank, so we feed it from a pair of 1 lb bottles in a Coleman Gemini carrier (https://www.coleman.com/gemini-propa...9708-A30C.html
And one unqualified recommendation - a couple of years ago when we were still camping out of a Coleman pop-up, we struggled endlessly using boards and blocks to level the trailer before discovering Anderson Camper Levelers (
). These things are without a doubt the best single trailer purchase I have EVER made.
