====== "Self-contained" RVs ======

Some camping areas, notably [[camping:lvta|LTVA]]s, require RVs to be "self-contained."  This example is from the BLM supplementary rules for LTVAs:

>Self-contained camping units must have a permanent, affixed waste water holding tank of 10-gallon minimum capacity. BLM does not consider port-a-potty systems, systems that utilize  portable  holding  tanks,  or  permanent  holding  tanks  of  less than 10-gallon capacity, to be self-contained.((https://www.blm.gov/style/medialib/blm/ca/pdf/elcentro.Par.98134.File.dat/LTVA_Supp_Rules.pdf))

Other requirements may be:
  * separate gray and black tanks
  * exterior gate valve for dumping tank[s]


Exceptions may be:
  - campsites near a vault toilet or restroom((https://www.blm.gov/style/medialib/blm/ca/pdf/elcentro.Par.98134.File.dat/LTVA_Supp_Rules.pdf))
  - [[toilet:composting|composting toilet]] in lieu (loo!) of black tank, ranger's discretion

Sometimes "self-contained" also means something like "livable space" for purposes of qualifying as an RV.  In this case it can also involve:
  * a separate electrical system (as with a [[electrical:12v:intro|house battery]])((http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/24550989/print/true.cfm))
  * the ability to [[food:cooking:stoves|cook]] and [[hvac:heating|heat]]((http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/24550989/print/true.cfm))
