Unfortunately, for the OP, or others looking at installing solar, I haven't seen any excellent sources of information, much is opinion, because the reality is, there isn't necessarily a best approach, and what works best, or the results you can expect can vary considerably due to external factors.
How you intend to use your setup, conditions they'll be operated in, and your abilities in maintaining your system all come into play. Areas you intend to camp and time of year, temperature you expect to camp in, what your realistic needs are etc. All these come in to play in determining "best" battery, type of controller, parallel/series etc. Put three engineers together on how to build the perfect system and you'll probably get three different answers.
