Park Model

 A Park Model (PM) is a tiny home, no more than 400 SF, a tad larger than our RV with slides extended.  It's similar to a mobile home in that it comes with wheels, but once placed on a site, it's seldom if ever moved.  The one below is a stock photo; the decking and steps are add-ons, not part of the basic unit.

Here are 2 more stock photos, showing typical interiors.

And here is the floor plan of the unit we're buying to place on our RV Resort lot near Usk, WA. Website: http://skookumrendezvous.com/

PMs have several advantages over RVs.  Household appliances are a biggie: RV appliances take a lot of abuse on bumpy roads and there's no lack of bumpy roads.  Some RV appliances are also dual/triple-powered to run on AC, DC and/or propane, meaning many more things to go haywire. 

Furnishing a PM is like furnishing any house.  You select your own stuff and place it wherever you want.  You can - and I have - modified and upgraded our RVs over the years but only a few things can be modified.

RVs have holding tanks for fresh water, gray water and black water, with fill-level gauges that never work.  Both the gray and the black can stink to high heaven if not carefully treated and monitored.  PMs have no holding tanks: everything goes down the sewer, so no stink.
