Installing Solar

Preparing for solar is nothing short of a root canal.  Now I've never had a root canal so I am just going off of others.  Solar prep is hard to plan, can be painful to the pocket and if done incorrectly can leave you stranded without power.  So far, that's all I've learned, not really but that's how it seems.
After purchasing our camper, I started researching the vast solar world in RVing.  Everyone has an opinion.  One person will tell you it's all about the watts, another will tell you it's all about the amps.  Others will tell you to put panels on every square inch of the camper while someone else will tell you it's all about the controllers and batteries.  And then there is the discussion of wiring, which I could write a novel about. 
Brands of panels I have come to understand doesn't really matter much.  Yes, reputable brands will give you 25 year warranties and others will have invaluable customer service and support.  Some, but not all, will have tons of information listed on their websites for easy learning while others won't.  It takes a lot of reading between the lines to get a grasp of it all. 
I have a rather extensive understanding of electricity and wiring.  I've had some in college classes and I have taught electrical engineering for many years.  I know the difference from series and parallel circuits which is a plus but reading some of these articles and blogs can make your head spin. 
I finally settled on getting a couple of panels and controller with a bluetooth output.  Took a run to the store to pick up a couple of 6 volt golf cart batteries (I'll be adding 2 more in the near future).  So far, I haven't really put any load on the system but from doing multiple readings of voltage and amps, it seems to be working like a charm.  Yes, I did a power audit before ordering but you never know til you get started if it will work.  I tried to mount the controller out of the way but accessible and the batteries are all tucked away.  I stilll have to mount a vent since I bought flooded batteries, it's all the rage to purchase decades old tech.  I couldn't justify the added cost of AGM or Lithium cells and if I maintain what I have correctly, what I got should last a long time.
I know I didn't write about which brands or any specifics in this post but I just wanted to let you know where my mindset was to start with.  I will post more specific information on my setup and photos to help others.
