-==== Thinking like an apartment-dweller ====+==== overcomplicating the power setup ====
  
 +Rube Goldberg has nothing on a subset of new vanfolk.  They dream up weird setups with multiple banks, sometimes of different chemistries.  Strange wiring setups that require frequent human intervention.
 +
 +The main reason for this is a lack of understanding about how the components actually work and what they can do.  This confusion turns into anxiety, which turns into "Ima throw a credit card around and see if that calms my nerves."    The proliferation of //power stations// has made this worse since they often have limitations that really can require esoteric hoop-jumping.
 +
 +The best way to calm those nerves (and get a system that works for minimal effort and cost) is:
 +
 +  - figure out [[electrical:12v:dailypowerrequirements|what you actually need, power-wise]]
 +  - figure out [[electrical:12v:power_mix|how you will recharge the bank]]  
 +  - learn what basic types of product[s] that will you meet those needs, preferably with no continued input from you
 +  - **read the specs and documentation** on the product[s]
 +  - //then// start looking for specific products and deals on those products
 +  - now you're finally ready to start buying stuff
 +
 +If you are a drama addict who needs chaos to function, here's how to make an expensive clusterfsck:
 +
 +  - [[opinion:frater_secessus:beginner_mistakes#buying_random_stuff|buy random shit]] because it's on sale, it looked kewl, because you lack self-control, or are in a drunken stupor
 +  - try to use it
 +  - find out it doesn't meet your needs because it wasn't designed to.  The specs and manuals spelled this out, but [insert beating of dead horse]
 +  - try to add on more parts and complication to see if it helps.  It doesn't, because you don't know what you're doing, how whole thing works,  or even trying to accomplish
 +  - rant online that the random products you bought are "shit", "utter trash", "garbage", etc because they work as designed, not as you wished/hoped.

 +==== Thinking like an apartment-dweller ====
  
 **A van is not an apartment**, so stop thinking that way.  A productive approach is to **start from nothing** then decide what you need to make your vanlife workable. Prefer non-electric approaches to electric ones.  This goes hand-in-hand with the math below. **Wanting all the amenities you had in a house or apartment** will cause disappointment, great expense, or both.     **A van is not an apartment**, so stop thinking that way.  A productive approach is to **start from nothing** then decide what you need to make your vanlife workable.
